alex bakes $24$ apple, blueberry, and cherry pies. The ratio of apple to blueberry to cherry pies is $1:4:3$. How many cherry pies did Alex bake?

Alex baked 9 cherry pies

Step-by-step explanation:

apple : blueberry : cherry = 1:4:3

apple + blueberry + cherry = 24

1 part: 24 / (1+4+3) = 24 / 8 = 3

* * Cherry has 3 parts: 3 x 3 = 9

check: apple = 3 x 1 = 3

blueberry: 3 x 4 = 12

12 + 3 + 9 = 24
