Answer
$2.5: 1.5=\frac{25}{15}=\frac{5}{3}=5: 3 $
$\text { OR } 2.5: 1.5=\frac{25}{10}: \frac{15}{10}=\frac{25}{10} \div \frac{15}{10} $
$=\frac{25}{10} \times \frac{10}{15}=\frac{25}{15}=\frac{5}{3}=5: 3$
$\text { OR } 2.5: 1.5=\frac{25}{10}: \frac{15}{10}=\frac{25}{10} \div \frac{15}{10} $
$=\frac{25}{10} \times \frac{10}{15}=\frac{25}{15}=\frac{5}{3}=5: 3$
