Question

By expressing the following in the form $\frac{p}{q}$, where $p$ and $q$ are integers and $q\ne 0$.

0.2 is equal to $\frac{1}{m}$, Find the value of m.

Answer 1

Since we do not know what 0.2 is, let us call it 'x' and so $x=0.2$.

Multiplying both sides of the equation by 10, we get,

$10x=10\times \left(0.2\right)=2$

Solving for x, we get

$x=\frac{2}{10}=\frac{1}{5}$
