Question

10. By what number should 18/33 be multiplied to get -9/11​

Answer 1

As per question,

We have to find the fraction, which when multiplied to $\frac{18}{33}$ gives $\frac{9}{11}$

So,

Let $\frac{x}{y}$ is the required number.

So,

$\frac{18}{33} \times \frac{x}{y} = \frac{9}{11}\\=> \frac{x}{y} = \frac{9}{11} \times \frac{33}{18}\\\frac{x}{y} = \frac{3}{2}$

Hence, when $\frac{3}{2}$ is multiplied to $\frac{18}{33}$ gives $\frac{9}{11}$.
