Question

Mark the correct alternative in the following question:

$\frac{1}{12}:\frac{1}{60}=$

(a) 4 : 1 (b) 1 : 4 (c) 5 : 1 (d) 1 : 5

Answer 1

Since,

$$\begin{gathered} \frac{1}{12}:\frac{1}{60} \\ =\frac{1}{12}÷\frac{1}{60} \\ =\frac{1}{12}\times \frac{60}{1} \\ =\frac{60}{12} \\ =\frac{5}{1} \\ =5:1 \end{gathered}$$

Hence, the correct alternative is option (c).
