Question

80 us 56% of what number?

Answer 1

80 is 56% of 142.9 rounded to the nearest 10th

Explanation:

First, when converting from a word problem to a math problem the word "is" is the same as equals or `=`.

"Percent" or "%" means "out of 100" or "per 100", Therefore 56% can be written as `56/100`.

When dealing with percents the word "of" means "times" or "to multiply".

Then, we can make "what" be or variable, let's call it `n`.

Putting this all together gives:

`80 = 56/100 xx n`

Solving this equation gives:

`100/56 xx 80 = 100/56 xx 56/100 xx n`

`8000/56 = cancel(100)/cancel(56) xx cancel(56)/cancel(100) xx n`

`142.9 = n` rounded to the nearest 10th
