In a school 8/15
of the students are boys. If the number of girls is 840, find the number of boys.
​

Answer 1

Answer:

So fraction of the girls is

1 - 8/15 = 7/15 .

So fraction of the girls is 7/15 and we know that number of girls is 840.

So

7/15 = 840

1/15 = 840/7 = 120

8/15 = 120*8 = 960.

So number of boys is 960.
