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

Can someone help me with this question please.

Answer:

6, 8, and 10.

Step-by-step explanation:

You could work this out with the pythagorean theorem, by proving that 6^2, 36, plus 8^2, 64, equals 100. The fastest way, however, is to use pythagorean triples. These are predetermined sets of numbers that work as side lengths for right triangles. The first two are 3, 4, and 5, which form a right triangle, and 6, 8, and 10, shown here.
