The ratio of boys to girls in the 9th grade is approximately 7 to 9. There are 228 girls. How many boys are there?

Question

_

Answer 1

The question gives a hint with the term, "Ratio."

To solve this problem, set up a ratio of b/g (b for boys and g for girls) and Solve for b.

b/g = 7/9

b/228 = 7/9 Fill in 228 (as given) for g for girls

b = (7 * 228) / 9 Multiply each side by 228

b = 177 boys

You have to round the answer to a whole number because you can't have a partial boy. Also, the original ratio of 7/9 was "approximately."
