Question
(i) You know that area of (RBSESolutions.com) a rectangle = length x breadth. But if length and breadth is given in fraction, then how will you find the area of rectangle?
(ii) Are you agree with that to find the area of a rectangle, we must know how to multiply two or more than fractional numbers?
Solution:
(i) If length and breadth are given in fractional numbers then the numerators are multiplied with numerators and denominators with denominators to find a fraction that is the area of a rectangle:
For example:
length = 4/5 unit and breadth = \(\frac { 3 }{ 7 }\)unit
Then area of rectangle = length x breadth
= \(\frac { 4 }{ 5 }\) x \(\frac { 3 }{ 7 }\) = \(\frac { 4\times 3 }{ 30 }\) = \(\frac { 5 }{ 7 }\)
= \(\frac { 12 }{ 35 }\) sq unit.

Question 1
The population of a village is increased (RBSESolutions.com) to 15000 from 12000 in last 10 years. Then what is the percentage growth of population ?
Solution:
Population of village = 12000
Increased population of village in last 10 year = 15000
Increase in population = (15000 – 12000) = 3000

Question 2
Express rate of growth or loss in the (RBSESolutions.com) form of percentage in the following :
(1) The cost of electricity per unit has increased to ₹6.00 from ₹3.50
(2) The cost of 100 envelopes has decreased to ₹80 from ₹100.
Solution:
(1) Original rate per unit = ₹3.50
Increased rate per unit = ₹6
increase = 6 – 3.50 = ₹2.50

(2)100 envelopes cost = ₹100
New price = ₹80
Decrease in price = 100 – 80 = ₹20
Decrease % = \(\frac { 20 }{ 100 }\) x 100% = 20%

Question 1
Mahaveer bought 5 bags of sugar for ₹16000. He (RBSESolutions.com) spent ₹200 for taxi fare, ₹120 for labour charges and ₹200 for transporttation charges. Find the selling price of per kg of sugar so as to earn a profit of ₹3 on each kg.
Solution:
Cost of 5 bags of sugar = ₹16000
Other expenses = ₹200 + ₹120 + ₹200
= ₹520
∴ Total C.P. of 5 bags of sugar
= ₹16000 + ₹520 = ₹16520
∵ Profit on 1 kg = ₹3
Profit on 5 bags or 500 kg sugar
= 500 x 3 = ₹1500
So, Profit = S.P – C.P
or S.P = C.P + Profit
= 16520+ 1500 = ₹18020
So, S.P. of 5 bags = ₹18020
S.P. of 1 bag = \(\frac { 1820 }{ 5 }\) = ₹3604

Question 2
Manoj bought a second hand car for ₹1,50,000. He spent ₹60,000 on Its (RBSESolutions.com) engine repair and ₹15000 on replacing the tyre tubes. Manoj sold this car to Jitendra for ₹2,10,000 Calculate loss or gain in this business.
Solution:
Cost of car = ₹1,50,000
Expense on engine = ₹60,000
Expense on tyre & tube = ₹15,000
Total cost price = ₹2,25,000
Selling price = ₹2,10,000
Manoj has a loss
So, Loss = C.P – S.P
= 2,25,000 – 2,10,000
Loss = ₹15,000
Manoj has a loss of ₹ 15,000

Question 2
Population of Rajasthan is 570 lac and population (RBSESolutions.com) of Uttar Pradesh is 1660 lac. Area of Rajasthan is 3 Lac square km and area of Uttar Pradesh is 2 lac square km.
(i) In both states how many people are per square km.
(ii) Which state is having less population density?
Solution:
(i) Population of Rajasthan = 570 lac
Area of Rajasthan = 3 lac sq. km
∴ Number of people per square km = \(\frac { 570 }{ 3 }\) = 190
And population (RBSESolutions.com) of Uttar Pradesh = 1660 lac
Area of Uttar Pradesh = 2 lac sq. km
∴ Number of people per square km
= \(\frac { 1660 }{ 2 }\)
= 830
(ii) Because per square km less people are living in Rajasthan. So, Rajasthan is having less population density.

Question 3

(a) 15% of 250 = \(\frac { 15 }{ 100 }\) x 250
= 15 x 2.5 = 37.5

(b) 1% of 1 hour = 1% of 60 minutes
= \(\frac { 1 }{ 100 }\) x 60 = \(\frac { 6 }{ 100 }\) minutes
= \(\frac { 6 }{ 10 }\) x 60 second = 36 second

(c) 20% of 2500 = \(\frac { 20 }{ 100 }\) x 2500
= 20 x 25 = 500

Write three such rational (RBSESolutions.com) numbers equivalent to \(\frac { -3 }{ 7 }\) in which the numerator is 24, – 60 and 75.
Solution:

Question 4
Write the following rational numbers in the (RBSESolutions.com) simplest from (standard forms) :

Solution:

Question 5
Represent the following rational numbers (RBSESolutions.com) on number line :

Solution:
(i) We know that \(\frac { 3 }{ 5 }\) is greater than 0, so \(\frac { 3 }{ 5 }\) will be in between 0 and 1.
Now to represent \(\frac { 3 }{ 5 }\) on number line, the distance between 0 and S is divided in 5 equal parts and take three parts from it to mark point P. This way point P represents point \(\frac { 3 }{ 5 }\) .

(ii) We know (RBSESolutions.com) that \(\frac { 7 }{ 8 }\) is greater than 0 and less than 1.
∴ \(\frac { 7 }{ 8 }\) will be in between 0 and 1.
Now to represent \(\frac { 7 }{ 8 }\) on number line, distance between 0 and 1 is divided in 8 equal parts and take 7 parts from it to mark point P. Thus point P represent point \(\frac { 7 }{ 8 }\).

(iii) We know that \(\frac { -8 }{ 3 }\) or -2\(\frac { 2 }{ 3 }\), is greater than -3 and less than – 2 so \(\frac { -8 }{ 3 }\), will be in between -2 and – 3.
Now on number line, the (RBSESolutions.com) distance between – 2 and – 3 divided in 3 equal parts and take 2 parts from it to mark point P. This way point P represents point \(\frac { -8 }{ 3 }\).

(iv) We know that -2\(\frac { 1 }{ 2 }\) or \(\frac { -5 }{ 2 }\), is greater from – 3 and less than – 2 so \(\frac { -5 }{ 2 }\) will be in between – 2 and -3.
Now to represent \(\frac { -5 }{ 2 }\) on number line, the distance between -2 and -3 is divided in 2 equal parts and take one part from it to mark point P.
This way point P represent (RBSESolutions.com) the point –\(\frac { 5 }{ 2 }\) ( -2\(\frac { 1 }{ 2 }\)) or number line.

(v) We know that \(\frac { 5 }{ 7 }\) is greater than 0 and less than 1.
\(\frac { 5 }{ 7 }\), will be in between 1 and 1.
Now to represent \(\frac { 5 }{ 7 }\) on number line, the distance between 0 and 1 is divided in 7 equal parts and take 5 parts to make point P. This way point P

represents \(\frac { 5 }{ 7 }\) on number line.

Question 6
Choose the correct (RBSESolutions.com) sign from <, >, = and fill in the blanks :

Solution:
(i) We know that positive rational numbers are greater than negative rational numbers

(ii) L.C.M. of (RBSESolutions.com) denominator 4 and 3 is 12

(iii) L.C.M. of (RBSESolutions.com) denominator – 5 and 3 is 15

(iv) L.C.M. of 7 and 2 is 14

(vi) We know that negative rational (RBSESolutions.com) numbers are smaller than positive rational number.

Question 7
Write five rational numbers between fol-lowing rational numbers :

Solution:

We know that integers (RBSESolutions.com) between -9 and -3 are
⇒ -8 < -7 < -6 < -5 < -4

∴ Five rational numbers between – 9 and – 3 will be:

We know that integers (RBSESolutions.com) between 0 and -6 are

∴ Five rational numbers between 0 and -1

∴ Five rational numbers (RBSESolutions.com) between -56 and – 50 are

We know that integers between 12 and 6 are :

∴ Five rational (RBSESolutions.com) numbers between \(\frac { 1 }{ 2 }\) and \(\frac { 1 }{ 4 }\) are

(v) We know that integers between 2 and -4 are:
-4 < -3 < -2 < -1 < 0 < 1 < 2
∴ Five rational numbers between \(\frac { 2 }{ 5 }\) and \(\frac { -4 }{ 5 }\) will be

Question 8
Write three more rational (RBSESolutions.com) numbers in each of the following :

Solution:

Question 9
Write the (RBSESolutions.com) following rational number in increasing order :

Solution:
(i) ∵ Denominators of given rational numbers are positive.
∴ L.C.M of 2, 2, 4 and 4 = 4 on making denominator of each = 4

∵ Denominators of (RBSESolutions.com) rational numbers are positive
∴ L.C.M. of 2, 4 and 7 = 28 on making the denominator of each = 28

∴ Increasing order is

∵ Denominator of rational (RBSESolutions.com) numbers are positive.
∴ L.C.M of 11, 15, 1, 1 and 15 = 165
on making denominator of each = 165

∵ Denominator of rational number are positive
∴ L.C.M of 5, 7, 6, 9 = 630 on making (RBSESolutions.com) denominator of each = 165

Question 10
Write the following rational (RBSESolutions.com) numbers is decreasing order :

Solution:

on making (RBSESolutions.com) the denominator 48 of each

∵ Denominator of rational number (RBSESolutions.com) are positive
∴ L.C.M of 6, 6, 9, 12 = 36
on making denominator 36 of each


on making (RBSESolutions.com) denominator 6 of each

on making (RBSESolutions.com) denominator 30 of each
