Answer 2

Answer:

ஃ The another number is 30 and also proved that the solution is correct.

Explanation:

To find the other number, we need to divide

$\sf 18 \div \frac{3}{5} = \frac{18}{1} \times \frac{5}{3} = \frac{18 \times 5}{1 \times 3} = \frac{90}{3}$

$\sf = 30$

Check:

$\sf \frac{3}{5} \times 30 = 18$

$\sf \frac{3}{5} \times \frac{30}{1} = 18$

$\sf \frac{3 \times 30}{5 \times 1} = 18$

$\sf \frac{90}{5} = 18$

$\sf 18 = 18$
