Problem Solving

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

My Strategy:

 8     12

girls  boys       

8:12     

8+12 =20

Double 8 and double 12

16:24

16+24=40

PROBLEM SOLVING

3x4=12  5x3=15  7x1=7  4x0=0  3x10=30

a)3x5 =15 5x3=15

c)$40+$15=$55
