Answer 2

The question is that we have to find the number By what number should 7/15 be divided to obtain 2/9.

let x be the number that should be divided from 7/15 to obtain 2/9

$\frac{ \frac{7}{15} }{ \frac{x}{1} } = \frac{2}{9} \\ \frac{7}{15} \times \frac{1}{x} = \frac{2}{9} \\ \frac{7 \times 9}{15} = 2x \\ \frac{7 \times 9}{15 \times 2} = \frac{7 \times 3}{5 \times 2} = \frac{21}{10}$

$\frac{21}{10}$

is the number divides 7/15 to obtain a 2/9

$\frac{7}{15} \div \frac{21}{10} = \frac{7}{15 } \times \frac{10}{21} = \frac{1}{3} \times \frac{2}{3} = \frac{2}{9}$

Therefore, the answer is 21/10.
