Question

The pie chart shows the favourite lesson of a group of students 20 students questioned chose maths and half of the rest chose pe how many of the students did not choose maths or pe ?

Answer 1

Answer:

10

Step-by-step explanation:

Half of the students chose maths and the half is 20 .

And half of the maths students chose PE so the number of students that chose PE are 10.

PE is just a quarter of the pie chart and maths half of the pie chart making the total of maths and PE 75% out of the whole pie chart.

That only leaves us with 25% to calculate and we already know the amount of PE which is also 25% out of the whole pie chart and PE is 10 .

So therefore, the answer is 10.
