ratio and poroportion

For every 8 girls in the school there are 12 boys.If there are 40 students in the school how many  are girls and how many  are boys?

My group strategy

Mason said double 12

Gideon said double 8

Double 8 =16

Double 12 =24

Total =40

Gideon we know 40 is double of 20

16;24

ratio and poroportion

Sally irons 8 shirt in 4 mins How long will it take her iron 1 shirt?

This is my strategy

8 shirts-4 mins

4 shirts-2mins

2 shirts-1mins

1 shirt-30sec
