Answer:

Grades 6 and 8

Step-by-step explanation:

If the relationship of girls to boys in two different grades are proportional, <u>they must have the same ratio</u>. To tackle this problem, we can find the <u>ratios</u> of genders in each grade and compare them.

Step 1, finding ratios:

Finding ratios is just like <u>simplifying fractions</u>. We will reduce the numbers by their<u> greatest common factors</u>.

  • GRADE 6:

9:12=\\3:4

  • GRADE 7:

12:18=\\2:3

  • GRADE 8:

15:20=\\3:4

  • GRADE 9:

25:36

<u>Can't be simplified!</u>

<u />

Step 2:

Notice how grades 6 and 8 both had a ratio of 3:4. We can conclude that these two grades have a proportional relationship between girls and boys.

<em>I hope this helps! Let me know if you have any questions :)</em>
