Question

At the start of the week, you could complete 12 push-ups. By the end of the week, you could complete 17 push-ups. Which proportion could you use to find the percent increase in the number of push-ups you can complete

Answer 1

It would be: 5/12 * 100 = 500/12 = 41.66%

So, your final answer is 41.66%

Hope this helps!

Answer 2

The percentage increase is equal to
`41.67\%`

The proportion to find the percentage increase is equal to
`(5)/(12)*100`

Explanation:

we know that

`12\ push-ups` ------> represent the
`100\%`

The increase of push-ups is equal to

`17-12=5\ push-ups`

by proportion

`(12)/(100)(push-ups)/(\%) =(5)/(x)(push-ups)/(\%)\\ \\x=(5)/(12)*100\\ \\x=41.67\%`

The percentage increase is equal to
`41.67\%`

The proportion to find the percentage increase is equal to
`(5)/(12)*100`
