Question

How do you solve `n/4=8/7`?

Answer 1

multiply to cancel out the denominator

Explanation:

you are given that `n/4`= `8/7`
we want to get rid of that divided by 4 on the left side
to undo division, we can multiply
but, because this is algebra, we have to multiply both sides by the same thing
so, multiply both sides by 4
`4*(n/4)=4*(8/7)`
cancel the 4s, and you are left with
`n=32/7`
