Question

A copy machine makes 153 copies in 4 minutes how many copies does it make per minute

Answer 1

4 mins = 153 copies

1 min = 153 ÷ 4 = 38.25 copies

-

Answer: 38.25 copies/min

Answer 2

Step 1 ) Create a fraction to represent the problem.

$\displaystyle\frac{153c}{4m}$

Step 2 ) Divide top and bottom by 4.

$\displaystyle\frac{153c}{4m}$

$\displaystyle\frac{153c}{4m}$ ÷ $\displaystyle\frac{4}{4} = \frac{38.25c}{1m}$

This shows that the total amount of copies the copier makes in one minute is...

$\framebox {38.25}$
