Answer
Find out the how many one fourth pieces can be made out of the leftover cake .
To proof
Let us assume that the number of one fourth pieces can be made out of the leftover cake be x.
As given
\(There\ are\ \frac{6}{8}\ of\ cake\ left\ over\ after\ a\ birthday\ party .\)
Than the equation become in the form
\(\frac{x\times1}{4} = \frac{6}{8}\)
Solving
\(x = \frac{6\times 4}{8}\)
\(x =\frac{6}{2}\)
x = 3
Therefore one fourth pieces are 3 made out of the leftover cake .
Hence proved
