Exercise 11 Page 177

Plot the numbers on a number line.

0.1, 12 %, 4/25

Practice makes perfect
We want to order the given numbers from least to greatest. 12 %, 0.1, 4/25 To do this, we will rewrite every number as a decimal number. At first, let's rewrite the percent. To do this, we ignore the percent symbol and move the decimal point two places to the left. Let's do it!
percent as decimal: 0.12
We found that 12 % as a decimal number is 0.12. Next, let's rewrite the fraction as a decimal number. To do this we will find an equivalent fraction with a denominator of 100. Let's go with 425!
4/25
4 * 4/25 * 4
16/100
0.16
Now, we know that 425 as a decimal number is 0.16. Let's take a look back at our set of numbers. 12 %, 0.1, 4/25 ⇕ 0.12, 0.1, 0.16 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 0.1, so it is the least from the list. The farthest to the right is 425, so it is the greatest.
opposite number

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 this! 0.1, 12 %, 4/25
