Question

Mrs. Smith’s class is making vests. Each vest uses 2/3 of a yard of fabric. How many vests can they make out of 18 yards of fabric?

Answer 1

27 vests

Explanation:

• If a vest is made out of 2/3 yard of fabric, then to know how many vest can be made with 18 yards, of fabric, we apply simple three rule, like this:

1 vest --------- 2/3 yard

x vest -------- 18 yards

• Then, to know how many vest can be made out of 18 yards of fabric ("x"), we divide 18 by (2/3):
  `(18)/((2)/(3)) =18(3)/(2) =24`.
