1. [latex]1\frac { 1 }{ 4 }[/latex] hour = …………. minutes

2. [latex]2\frac { 1 }{ 2 }[/latex] hour = …………. minutes

3. [latex]5\frac { 3 }{ 4 }[/latex] hour = …………. minutes

4. [latex]3\frac { 1 }{ 5 }[/latex] hour = …………. minutes

Solution.

(1) [latex]1\frac { 1 }{ 4 }[/latex] hour = 1 hour + [latex]\frac { 1 }{ 4 }[/latex] hour

= 1 x 60 minutes + [latex]\frac { 1 }{ 4 }[/latex] x 60 minutes

= 60 minutes + 15 minutes = 75 minutes

(2) [latex]2\frac { 1 }{ 2 }[/latex] hour = 2 hour + [latex]\frac { 1 }{ 2 }[/latex] hour

= 2 x 60 minutes + [latex]\frac { 1 }{ 2 }[/latex] x 60 minutes,

= 120 minutes + 30 minutes

= 150 minutes

(3) [latex]5\frac { 3 }{ 4 }[/latex] hour = 5 hour + [latex]\frac { 3 }{ 4 }[/latex] hour

= 5 x 60 minutes + [latex]\frac { 3 }{ 4 }[/latex] x 60 minutes

= 300 minutes + 3 x 15 minutes

= 300 minutes + 45 minutes

= 345 minutes

(4) [latex]3\frac { 1 }{ 5 }[/latex] hour = 3 hour + [latex]\frac { 1 }{ 5 }[/latex] hour

= 3 x 60 minutes + [latex]\frac { 1 }{ 5 }[/latex] x 60 minutes

= 180 minutes + 12 minutes

= 192 minutes

Solution.

1. 20 minutes = 20 x 60 seconds

= 1200 seconds

2. [latex]6\frac { 1 }{ 2 }[/latex] minutes = 6 minute + [latex]\frac { 1 }{ 2 }[/latex] minute

= 6 x 60 seconds + [latex]\frac { 1 }{ 2 }[/latex] x 60 seconds

= 360 seconds + 30 seconds

= 390 seconds

3. [latex]15\frac { 1 }{ 4 }[/latex] minutes = 15 minute + [latex]\frac { 1 }{ 4 }[/latex] minute

= 15 x 60 seconds + [latex]\frac { 1 }{ 4 }[/latex] x 60 seconds

= 900 seconds + 15 seconds

= 915 seconds

4. 4 hour = 4 x 60 minutes

= 240 minute = 240 x 60 seconds

= 14400 seconds

5. [latex]2\frac { 3 }{ 4 }[/latex] hour = 2 hour + [latex]\frac { 3 }{ 4 }[/latex]hour

= 2 x 60 minutes + [latex]\frac { 3 }{ 4 }[/latex] x 60 minutes

= 120 minutes + 3 x 15 minutes

= 120 minutes + 45 minutes
