Exercise 20 Page 277

Let's approach ordering the given set from least to greatest one number at a time.

First Value

First, we have 7.49. It is in decimal form, we do not have to rewrite this number. We will rewrite the other numbers as decimals to order them. 7.49

Second Value

Next, we have 7 4950. Let's rewrite this number as a decimal.

Next, we can compare this number to 7.49. 7.49 < 7.98 ⇔ 7.49 < 7 4950

Third Value

Let's rewrite the third value, 7.5 %. Recall that we can rewrite percent as a decimal. Let's take a look.

In this form, we can compare this number to the other two. 7.49 < 7.5 < 7 4950 ⇕ 7.49 < 7.5 % < 7 4950

Combining the Numbers

Now, we can write the set in order from least to greatest. {7.49, 7.5 %, 7 4950 }
