16\times \frac{5}{4}=y
Multiply both sides by \frac{5}{4}, the reciprocal of \frac{4}{5}.
\frac{16\times 5}{4}=y
Express 16\times \frac{5}{4} as a single fraction.
\frac{80}{4}=y
Multiply 16 and 5 to get 80.
20=y
Divide 80 by 4 to get 20.
y=20
Swap sides so that all variable terms are on the left hand side.
