Question

forty children were asked to name their favourite sport. how many of the children have football as their favourite sport?

Explanation:

Step1: Assume equal - sized sectors for simplicity (since no angle information).

If we assume the pie - chart is divided evenly among the sports and we know there are 5 sports shown (Football, Tennis, Hockey, Netball, Other) and a total of 40 children were asked.

Step2: Calculate the number of children for each sport if evenly divided.

The number of children per sport if evenly divided is $\frac{40}{5}=8$. But we need to estimate from the pie - chart. By visual inspection, the 'Football' sector seems to be about $\frac{1}{4}$ of the whole pie - chart.

Step3: Calculate the number of children who like football.

The number of children who like football is $\frac{1}{4}\times40 = 10$.

Answer:

10
