0.125 = 1/8

Since LHS is (0.125)^2, we need raise the power of RHS by 2
i.e. (1/8)^2 = 1/64
Hence Answer is E

B. 1/12

D. 1/32
E. 1/64

\(0.125 = \frac{1}{8}\)

So, \((0.125)^2 = ( \frac{1}{8} )^2\)

Or, \((0.125)^2 = \frac{1}{64}\)

Hence, answer will be (E) \(\frac{1}{64}\)

Hi,

Although we would generally know that 0.125=1/8..
But say we do not know the choices should get us to our answer..

We are looking for a square..
So the fraction too should be a square of a fraction..
ONLY 1/16 and 1/64 are square.

Let's see these two now..
\(\frac{1}{16}=\frac{(1}{4)}^2\)...
Now 1/4 is 0.25, but we are looking for 0.125, so 1/64 is the answer

We can convert 0.125 to a fraction.

0.125 = 125/1000 = 5/40 = 1/8

(1/8)^2 = 1/64

Answer: E
