Answer 1

$m \times \frac{30 \times 5}{100 \times 100} = 18 \\ \\ \\ m \times \frac{150}{10000} = 18 \\ \\ \\ m = \frac{18 \times 10000}{150} = \frac{6 \times 10000}{50} = \frac{60000}{50 } \\ \\ \\ = 1200 \\ \\ \\ \\ hope \: it \: helps...$

Answer 2

$m \times \frac{30 \times 5}{100 \times 100} = 18 \\ m = \frac{18 \times 100 \times 100}{30 \times 5} \\ m = 1200$
