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#
