Question

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

293 boys
177 boys
226 boys
224 boys

Answer 1

177 boys

Explanation:

Let number of boys be b and number of girls be g

ratio of b/g = 7/9

= b/228 = 7/9 (substituting 228 for number of girls)

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

Therfore b = 177 boys (rounded to the nearest whole number)
