Q:

$\frac{1}{8}$ as a decimal?

A) 0.375	B) 0.247
C) 0.214	D) 0.125

Answer & Explanation Answer: D) 0.125

Explanation:

Here $\frac{1}{8}$ in decimal means 8th part in 1.

We know that $\frac{1}{10}$ = 0.1

Then, $\frac{1}{8} = ?$

=> $? = \frac{\frac{1}{8} x 0.1}{\frac{1}{10}} = \frac{0.1 x 10}{8} = \frac{0.5}{4} \frac{1}{8} = 0.125$
