We want to order the given numbers from least to greatest.
0.15 %, 3/20, 0.015
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!
We found that 0.15 % as a decimal number is 0.0015. 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 320!
Now, we know that 320 as a decimal number is 0.15. Let's take a look back at our set of numbers.
0.15 %, 3/20, 0.015 ⇕
0.0015, 0.15, 0.015
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 0.15 %, so it is the least from the list. The farthest to the right is 320, 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!
0.15 %, 0.015, 3/20
