Question

3/25 + (8/35÷4/21) ×7/30​

Answer 1

$\frac{3}{25} + ( \frac{8}{35} \div \frac{4}{21} ) \times \frac{7}{30} \\ \\ = > \frac{3}{25} + ( \frac{8}{35} \times \frac{21}{4} ) \times \frac{7}{30} \\ \\ = > \frac{3}{25} + \frac{6}{5} \times \frac{7}{30} \\ \\ = > \frac{3}{25} + \frac{42}{150} \\ \\ = > \frac{18 + 42}{150} = \frac{60}{150} = \frac{2}{5}$
