Step-by-step explanation:this is not true
The group that had the highest percentage of students that like Sports is group B.
The group that had the less percentage of students that like English is group A.
the percentage of students like Math in group A is 30% and 10% in group B
<h3>What are the percentages?</h3>
A pie chart is a graph that displays information in a circle. The circle is divided into slices which represent a numerical proportion. The sum of angles in a pie chart is 360 degrees
Percentage of students that like sports in:
- Group A = [20 / (20 + 15 + 5 + 10)] x 100 = 40%
- Group B = [22 / (5 + 4 + 9 + 22)] x 100 = 55%
Percentage of students that like English in:
- Group A = [5 / (20 + 15 + 5 + 10)] x 100 = 10%
- Group B = [5 / (5 + 4 + 9 + 22)] x 100 = 22.5%
Percentage of students that like Maths in:
Group A = [15 / (20 + 15 + 5 + 10)] x 100 = 30%
- Group B = [4 / (5 + 4 + 9 + 22)] x 100 = 10%
