Question 3.
To stich a pant, 1 meter 20 cm cloth is required. Find the length of the remaining cloth after cutting cloth for 15 pants from a lot of 28 m cloth.
Solution:
Cloth required for one pant
= 1 metre 20 centimetre
= 120 centimetre
Cloth required for 15 pants
= 15 × 120 centimetres
= 1800 centimetres
Cloth in one roll = 28 metres = 28 × 100
= 2800 centimetres
Remaining cloth length = 2800-1800
= 1000 centimetres
= 10 × 100 centimetres
= 10 metres

Question 4.
A rope of 28 m length is to be cut into 8 equal pieces. Find the length of each piece.
Solution: Length of Rope = 28 metres
= 28 × 100 centimetres
= 2800 centimetres
Number of pieces = 8
Length of one pieces = 2800 ÷ 8
= 350 centimetres
= 3 metres 50 centimetres

Question 5.
A rope is 3 m long. Rani cuts a piece of 1 m 5 cm from that rope. Write the length of the remaining rope in metres and centimetres.
Solution:
Length of Rope = 3 metres
= 3 × 100 cm
= 300 cm
Part cut from the rope = 1 metre 5 centimetres
= 100 cm.+5 cm.
= 105 cm.
length of remaining rope
= 300-105
= 195 cm
= 1 metre 95 centimetres

= 690 centimetres
Available cloth = 10 metres
= 10 × 100 centimetres
= 1000 centimetres
Cloth remaining after making 3 kurtas
= 1000 – 690 cm
= 310 cm
= 3 metres 10 centimetres

The length of one rug is 7 metres 30 centimetres. Tell what will be the length of 7 such rugs?
Solution:
Length of one rug
= 7 metres 30 centimetres
= (7 × 100) cm.+30 cm.
= 700 cm.+30 cm.
