Answer 1

Convert mixed numbers into an improper fraction:

A mixed number $a\frac{b}{c}$ is converted into an improper fraction as follows:

$a\frac{b}{c}=\frac{(a\times c)+b}{c}$

We have to convert $1\frac{1}{4}$ into an improper fraction.

$$\begin{gathered} \therefore 1\frac{1}{4}=\frac{(1\times 4)+1}{4} \\ \Rightarrow =\frac{5}{4} \end{gathered}$$

Hence, the required improper fraction is$\frac{5}{4}$.
