Question

A teacher asks her pupils what their favourite school subject was. 3 pupils said pe was their favourite subject. how many pupils said maths was their favourite subject

Answer 1

The answer is 15, I don't really have an explanation because the question can be different than yours. My question was the same but it had a pie chart so yeah. I'll explain how I got that using the question I had.

So 3 pupils = 27 degrees and the pupils that said that maths was their favourite subject was 135 degrees. All I did was divided 135 by 27= 5 and then multiplied that by 3 so 5x3= 15.

Hope this helped! Sorry i'm not the best when it comes to explaining lol.

Answer 2

15 pupils said maths was their favourite subject

GIVEN:- PIE CHART

TO FIND:- how many pupils said maths was their favourite subject

SOLUTION:-

As we can observe that 27° is equal to the number of pupils who said PE was their favourite subject.

Which means,

27° = 3 pupils

According to the unitary method

1° $= \frac{3}{27} \\ = \frac{1}{9}$

And we can observe that 135° is equal to the number of pupils who said maths was their favourite subject.

we need to simply multiply pupils by 1° with 135

Pupils that said maths was their favourite subject

$= \frac{1}{9} \times 135 \\ = 15$

Hence, 15 pupils said maths was their favourite subject
