The ratio of blue to yellow marbles is 7 to 9. i f there are 28 blue marbles in a jar, how many yellow marbles are there?

28/7 = 4*9 = 36

Just convert the number of blue balls to 1 unit and then multiply by the ratio of yellow balls.

Hey There!

This is a multi-step problem. First, you dive 28/7, you should get four. Then you multiply 4*9, you should get 36. So if there are 28 blue marbles in a jar, there should be 36 yellow marbles.

Hope This Helped ;)

8-2x+3x2=6 and six is your answer

I’m not gonna do that
