The pie chart shows what a group of children has chosen as their favourite colour. The same information is shown in a bar graph, but the names of the colours are not shown on the bar graph. How many children chose yellow and red as their favourite colour?

1. Read the values from the bar graph

The lengths of the four bars are $8$, $12$, $20$, and $32$.

2. Match the colours to the bar values using the pie chart's relative sizes

From the pie chart, the sectors in increasing order of size are Blue, Red, Green, and Yellow.
Matching these to the bar values in increasing order:

• Blue = $8$
• Red = $12$
• Green = $20$
• Yellow = $32$

3. Calculate the total number of children who chose yellow and red

$\text{Yellow} + \text{Red} = 32 + 12 = 44$
