Find ounces then divide 1.12 by 8.2 , if pounds then divide by [ 8.2 / 16 ] <span>
</span>
so in each group of 7 (3+4) there are 3 boys and 4 girls
there are 10 groups of 7 so
the number of boys is 10x3=30
the number of girls is 10x4=40
Your total bill would be 24.00. Split 3 ways, you would each pay 8.00. As 24 divided by 3 = 8.
