Question

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

Answer 1

Step 1 ) Create a fraction to represent the problem.

`\displaystyle(153c)/(4m)`

Step 2 ) Divide top and bottom by 4.

`\displaystyle(153c)/(4m)`

`\displaystyle(153c)/(4m)` ÷
`\displaystyle(4)/(4) = (38.25c)/(1m)`

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

`\framebox {38.25}`
