Answer:

Problem 1:90;48,42;16,32,28,14

Problem 2:180;60,120;12,48,30,90

Step-by-step explanation:

Problem 1:

There are 90 pupils at a primary school,so the first number is 90

48 of the pupils are girls, so the number of boys is 90-48=42

[tex]\frac{1}{3}[/tex] of the girls  play football, so the number of girls  who plays football is [tex]\frac{1}{3} \times48=16[/tex],the number of girls  who does not play football is48-16=32

[tex]\frac{2}{3}[/tex] of the boys play football,so the number of boys  who plays football is [tex]\frac{2}{3} \times42=28[/tex],the number of boys  who does not play football is 42-28=14

Problem 2:

There are 180 apples in a grocery store,so the first number is 180

[tex]\frac{1}{3}[/tex]of the apples are red,so the number of red apples is [tex]180\times\frac{1}{3} =60[/tex]

,the number of green apples is 180-60=120. [tex]\frac{1}{5}[/tex] of the red applesare bruised,[tex]\frac{1}{5} \times60=12[/tex],so the number of red apples not bruised is 60-12=48.   [tex]\frac{1}{4}[/tex] of the green apples are bruised,[tex]120\times\frac{1}{4} =30[/tex],so the number of green  apples not bruised is 120-30=90.
