Question

After counting all the intermediate school students, the principal came to the conclusion that 4 out of every 7 students was a boy. If there are 651 students in the building, how many of those students are boys? Hint: Find an equivalent ratio/proportion!

Answer 1

372

Explanation:

4 out of 7 is 4/7. So just multiply 651 by 4/7

651 x 4 is 2604

2604 divided by 7 is 372.

If you turn 4/7 into a decimal, It is about 57%

And 57% of 651 is about 372 so it is checked.
