Question

The pie-chart shows the favourite colours of the students of grade V. What is the fraction of students who like red colour. Express your answer in the lowest fraction.

• A. $\frac{2}{9}$
• B. $\frac{4}{15}$
• C. $\frac{1}{3}$
• D. $\frac{8}{45}$

Answer 1

The correct option is A

$\frac{2}{9}$

The total number of students in class V = 10 + 12 + 8 + 15 = 45
From the pie-chart, number of students who like red = 10
Hence, the required fraction is given by $\frac{10}{45}$.
We can see that both numerator and denominator have a common factor: 5.
$\frac{10÷5}{45÷5}=\frac{2}{9}$
Hence the required fractions is $\frac{2}{9}$.
