\[\frac{3}{5},1\times 2,\frac{}{3}\times 1\times \frac{1}{30}\]
Simplify \(1\times 2\) to \(2\).
\[\frac{3}{5},2,\frac{}{3}\times 1\times \frac{1}{30}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{3}{5},2,\frac{\times 1\times 1}{3\times 30}\]
Simplify \(\times 1\) to .
\[\frac{3}{5},2,\times \frac{1}{3\times 30}\]
Simplify \(3\times 30\) to \(90\).
\[\frac{3}{5},2,\times \frac{1}{90}\]
Simplify \(\times \frac{1}{90}\) to \(\frac{1}{90}\).
\[\frac{3}{5},2,\frac{1}{90}\]
