Question

The ratio of girls to boys in the 6th grade is 6 to 7. How many girls are there if there are 364 total students?

Answer 1

Answer:

168 girls

Step-by-step explanation:

×=number of kids

6×= number of girls

7×= number of boys

6x+7x= 364

13x=364

364÷13=28

6(28)=168

Answer 2

Step-by-step explanation:

If the ratio is 6:7 the students should divide nicely into 6+7=13 parts.  Six of those parts are girls, seven of those parts are boys.

364 / 13 = 28

So 6 × 28 = 168 girls

Answer: 168

Check:

7 × 28 = 196 boys

168 + 196 = 364, good
