Question

If $\frac{45}{60}$ is equivalent to $\frac{3}{x}$, then the value of x is

(a) 3
(b) 6
(c) 4
(d) 9

Answer 1

$$\begin{gathered} \frac{45}{60}=\frac{45÷15}{60÷15}=\frac{3}{4} \\ \mathrm{It}\mathrm{is}\mathrm{given}\mathrm{that}\frac{45}{60}\mathrm{is}\mathrm{equivalent}\mathrm{to}\frac{3}{x}. \\ \therefore \frac{3}{4}=\frac{3}{x} \\ \Rightarrow x=4 \end{gathered}$$

Hence, the correct option is (c).
