Exercise 4 Page 13

A rate is a special type of ratio that compares quantities with different kinds of units. A unit rate is a rate that has been reduced to have a denominator of 1 unit. We are given the following rate. $ 7.40in 5pounds Let's write this rate as a fraction. $ 7.40/5pounds To find the unit rate, we need to write an equivalent rate with a denominator of 1 pound. Let's ignore the units for simplicity.
