Question

What number should be divided by root0.25 to give the result 25

Answer 1

Answer:

Hey there!

Let the number be x

Then,  

\frac{x}{ \sqrt{0.25} } = 25

\frac{x}{ \sqrt{ \frac{1}{4} } } = 25

\frac{x}{ \frac{1}{2} } = 25

2x = 25

x = 25/5  

= 12.5  

Hence, a) 12.5 Is the answer.

Hope it helps!
