Question

2/3:2/5 and 1/9:1/15

Answer 1

Answer:

$\frac{2}{3} : \frac{2}{5} \\ = \frac{2}{3} \div \frac{2}{5} \\ = \frac{2}{3} \times \frac{5}{2} \\ = \frac{5}{3}$

$\frac{1}{9} : \frac{1}{15} \\ = \frac{1}{9} \div \frac{1}{15} \\ = \frac{1}{9} \times 15 \\ = \frac{15}{9} \\ = \frac{5(3)}{3(3)} \\ = \frac{5}{3}$
