Use this rule: \(a \times \frac{b}{c}=\frac{ab}{c}\).
\[\frac{1\times 3}{20},\frac{6}{25},\times \frac{15}{-4}\]
Simplify \(1\times 3\) to \(3\).
\[\frac{3}{20},\frac{6}{25},\times \frac{15}{-4}\]
Move the negative sign to the left.
\[\frac{3}{20},\frac{6}{25},-\times \frac{15}{4}\]
Simplify \(\times \frac{15}{4}\) to \(\frac{15}{4}\).
\[\frac{3}{20},\frac{6}{25},-\frac{15}{4}\]
3/20,6/25,-15/4
