Question

Mr. Lee can paint 20 chairs in t hours. Find, in terms of t, the time taken by Mr. Lee to paint 7 chairs.

Answer 1

We are given

Mr. Lee can paint 20 chairs in t hours

so,

`20 chairs=t hours`

now, we can find for 1 chair

so, we can divide both sides by 20

`1 chair=(t)/(20) hours`

now, we can multiply both sides by 7

`7*1 chair=7*(t)/(20) hours`

`7chairs=(7t)/(20) hours`....................Answer
