## Text Solution

What is Known?

Fractional numbers.

What is Unknown?

Conversion of Fractional numbers into percentage.

Reasoning:

To convert fraction into percentage we will have to multiply the fraction by $$100$$ because $$1\%$$ means $$1$$ part of $$100$$ i.e. $$1/100.$$

Steps:

\begin {align}{\rm{(a)}}\quad\,\frac{1}{8} &= \frac{1}{8} \times 100 \% \\&= 12.5\% \end{align}

\begin {align}{\rm{(b)}}\quad\frac{5}{4} &= \frac{5}{4} \times 100\% \\&= 125 \% \end{align}

\begin {align}{\rm{(c)}}\quad\frac{3}{{40}} &= \frac{3}{{40}} \times 100\% \\&= 7.5 \% \end{align}

\begin {align}{\rm{(d)}}\quad\frac{2}{7} &= \frac{2}{7} \times 100\% \\&= 28\frac{4}{7} \% \end{align}
