Im trying to find out the ratio of the yellow m&m's

Question

The ratio of green M & M’s to yellow M & M’s in a bag is 11:9. If there are 66 green M & M’s in

the bag, how many yellow M & M’s are there?

Answer 1

Hi Ana,

The ratio means that for every 11 green M&Ms in the bag, there are 9 yellow ones.

There are 66 green M&Ms in the bag. This is 11 x 6. So, since there are 11 x 6 green M&Ms in the bag, there must be 9 x 6 yellow ones! 9 x 6 = 54 yellow M&Ms.

As an equation, you write it as 11/9 = 66/x. Then cross multiply 11x = 66*9. Divide by 11 so x = 6*9 = 54.

Answer 2

g/y = 11/9 = 66/x

1/9 = 6/x

x = 9(6) = 54

54 yellows when 66 greens

Answer 3

G/Y = 11/9 = 66/Y

Cross multiply.

11Y = 9*66 = 594

Y = 594/11 = 54

54 Yellow
