Exercise 5 Page 185

We want to complete a table. We can use the portion where both values are known to find the missing values.

We know that we loose 32 pounds in 1/12 years. Let's write this as a ratio. 32pounds/112years or 32/112We will use this rate to find the missing values.

First Value

We can find an equivalent ratio with a denominator of 32 to find how many pounds we loose in 32 years.

We loose 27 pounds in 32 years.

Second Value

Now, we can find an equivalent ratio with a numerator of 212 to find how long it takes us to loose 212 pounds.

We loose 212 pounds in 712 years.

The equivalent ratios are 32: 112, 27: 32, and 212: 712.
