Question 3(a):

Express the following as improper fraction:

$7\frac{3}{4}$

Answer 1

Suppose we have a mixed fraction as: $\text{Whole}\frac{\text{Numerator}}{\text{Denominator}}$,

then its improper fraction is given as: $\frac{\text{Whole}\times \text{Denominator + Numerator}}{\text{Denominator}}$

For $7\frac{3}{4}$, on substituting the values we get:

$7\frac{3}{4}=\frac{(7\times 4)+3}{4}=\frac{28+3}{4}=\frac{31}{4}$
