Exercise 10 Page 417

Plot the numbers on a number line.

3/4, 78 %, 85 % , 7/8, 0.88

We want to order the given numbers from least to greatest. 7/8, 85 % , 0.88, 3/4, 78 % To do this, we will rewrite every number as a decimal number. Let's start with the percents. 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: 0.38
We found that 85 % as a decimal number is 0.85. Let's take a look at 78 %.
percent as decimal: 0.38
The decimal form of 78 % is 0.78. Next, let's rewrite fractions as decimal numbers. We will find equivalent fractions with a denominator of 100. Let's start with 78.
7/8
7 * 12.5/8 * 12.5
87.5/100
0.875
Now we know that 78 as a decimal number is 0.875. Let's continue with 34.
3/4
3 * 25/4 * 25
75/100
0.75
The decimal form of 34 is 0.75. Let's rewrite all of our numbers. 7/8, 85 % , 0.88, 3/4, 78 % ⇕ 0.875, 0.85, 0.88, 0.75, 0.78 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 34, so it is the least from the list. The farthest to the right is 0.88, 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 it! 3/4, 78 %, 85 % , 7/8, 0.88
