Question

The table shows whether pupils in a class have school dinners

Answer 1

Q 1 is 60%
Q 2 is 65%

Answer 2

Answer:

Percentage of boys have school dinners: 60%

Percentage of pupils in this class have school dinners: 65%

Step-by-step explanation:

1. There are: 6+4 = 10 boys in the class ->  corresponding to 100 %

1 boy is corresponding to 100% :10 = 10%

6 in 10 have school dinners -> 10% x 6 = 60%

2. There are 10( boys) + 7 (girls) + 3 (girls) = 20 pupils in the class -> corresponding to 100%

1 pupil is corresponding to 100% : 20 = 5%

There are : 6 + 7 = 13 pupils who have school dinners

13 in 20 have school dinners -> 5% x 13 = 65%
