A class of 40 puplis. 2/5 of them are boys How many are girls
There are 24 girls in the class.
- Well, since 2/5 of the class are boys, and there are 40 pupils in the class, we first must get the 1/5 of 40(Divide 40 & 5, 40 divided y 5 is 8.)
- Now that we have the 1/5 if 40, we must multiply is by 2, to get the 2/5 if 40 (8x2 = 16.) So there are 16 boys in the class.
- Now that we know the number of boys in the class, we now just need to subtract the number of pupils and the number of boys in the class(40–16.)
- 40-16 =24
So there are 24 girls in the class.
