Exercise 9 Page 417

Plot the numbers on a number line.

0.2, 24 %, 1/4, 0.32, 7/20

We want to order the given numbers from least to greatest. 24 %, 1/4, 0.2, 7/20, 0.32 To do this, we will rewrite every number as a decimal number. Let's start by rewriting the percent as a decimal. To do this, we ignore the percent symbol and move the decimal point two places to the left.
percent as decimal: 0.38
We found that 24 % as a decimal number is 0.24. Next, let's rewrite fractions as decimal numbers. We will find equivalent fractions with a denominator of 100. Let's start with 14.
1/4
1 * 25/4 * 25
25/100
0.25
Now we know that 14 as a decimal number is 0.25. Let's continue with 720.
7/20
7 * 5/20 * 5
35/100
0.35
The decimal form of 720 is 0.35. Let's rewrite our set of numbers. 24 %, 1/4, 0.2, 7/20, 0.32 ⇕ 0.24, 0.25, 0.2, 0.35, 0.32 Now we can write the given numbers in order from least to greatest by plotting them on a number line.
plotting point
The number that is the farthest to the left is 0.2, so it is the least from the list. The farthest to the right is 720, so it is the greatest.

Finally, we can write the values in order from least to greatest by moving from left to right on the number line. Let's do it! 0.2, 24 %, 1/4, 0.32, 7/20
