We want to order the given numbers from least to greatest.
3/10, 15 %, 0.2, 3/8, 0.09
To do this, we will rewrite every number as a decimal number. At first, let's rewrite the percents. To do this, we ignore the percent symbol and move the decimal point two places to the left. Let's do it!
We found that 15 % as a decimal number is 0.15. Next, let's rewrite fractions as decimal numbers. To do this we will find an equivalent fraction with a denominator of 100. Let's start with 310.
Decimal form of 38 is 0.375. Let's take a look back at our set of numbers.
3/10, 15 %, 0.2, 3/8, 0.09 ⇕
0.30, 0.15, 0.2, 0.375, 0.09
Now, we can write the given numbers in order from least to greatest by plotting them on a number line.
The number that is the farthest to the left is 0.09, so it is the least from the list. The farthest to the right is 38, 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 this!
0.09, 15 %, 0.2, 3/10, 3/8
