Answer:

81 boys

Step-by-step explanation:

There are two ways to figure this out. Both ways are correct.

1. Fractions

9/7=x/63

from here you cross multiply

7x=9×63

7x=567

now to get x by itself you divide by 7

x=567÷7

x=81

2. If you have 63 girls and 7 girls to each group. You can divide 63 by 7 and find out how many groups you have which is 9. 9 groups, 7 girls each. For every 7 girls there are 9 boys. 9×9 ( 9 groups, 9 boys each)

9×9=81
