Question

A store manager orders T-shirts so that 15 out of every 35 are a medium. How many medium T-shirts would you expect to find when there are 126 T-shirts on a rack?

Answer 1

75

Explanation:

Set up a proportion

15/25 = x/126 Cross Multiply

25x = 15 *126 Divide by 25. Combine terms on the right

x = 1890 / 25

x = 75.6 Now we have to make a decision

What do we do about the 0.6?

Normally you would round to 76. But what is 0.6 of a shirt? We should round down.
