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?

75

Step-by-step 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.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
