40\times \frac{2}{5}=y
Multiply both sides by \frac{2}{5}, the reciprocal of \frac{5}{2}.
\frac{40\times 2}{5}=y
Express 40\times \frac{2}{5} as a single fraction.
\frac{80}{5}=y
Multiply 40 and 2 to get 80.
16=y
Divide 80 by 5 to get 16.
y=16
Swap sides so that all variable terms are on the left hand side.
