21\times \frac{\frac{2}{3}}{\frac{1}{7}}=s
Multiply both sides of the equation by 21.
21\times \frac{2}{3}\times 7=s
Divide \frac{2}{3} by \frac{1}{7} by multiplying \frac{2}{3} by the reciprocal of \frac{1}{7}.
21\times \frac{2\times 7}{3}=s
Express \frac{2}{3}\times 7 as a single fraction.
21\times \frac{14}{3}=s
Multiply 2 and 7 to get 14.
\frac{21\times 14}{3}=s
Express 21\times \frac{14}{3} as a single fraction.
\frac{294}{3}=s
Multiply 21 and 14 to get 294.
98=s
Divide 294 by 3 to get 98.
s=98
Swap sides so that all variable terms are on the left hand side.
