Question

Each marble bag sold by Latoya’s Marble Company contains 7 purple marbles for every 4 red marbles. If a bad has 32 red marbles, how many purple marbles does it contain?

Answer 1

Explanation:

7 purple to 4 red = x purple to 32 red

7 / 4 = x / 32....cross multiply because this is a proportion

(4)(x) = (7)(32)

4x = 224

x = 224/4

x = 56 purple <==
