Question

Express the given as improper fractions :

$7\frac{3}{4}$

Answer 1

We can change a mixed number to a fraction by adding.

$$\begin{gathered} 7\frac{3}{4}=7+\frac{3}{4} \\ =\frac{7}{1}+\frac{3}{4} \\ =\frac{28}{4}+\frac{3}{4} \\ =\frac{31}{4} \end{gathered}$$

Hence the required answer is $\frac{31}{4}$
