Final answer:
To order the numbers 10.5%, 3/20, and 0.015 from least to greatest, first convert them to decimal form, resulting in 0.015, 0.105, and 0.15 respectively. Ordered from least to greatest, the numbers are 0.015, 10.5%, 3/20.
Step-by-step explanation:
The question involves ordering the numbers 10.5%, 3/20, and 0.015 from least to greatest. To compare these effectively, we'll convert each to a decimal form:
10.5% can be written as 0.105. (Recall that to convert a percentage to a decimal, divide by 100.)
3/20 as a decimal is 0.15. (Dividing 3 by 20 gives 0.15.)
0.015 is already in decimal form.
Now, looking at the decimal equivalents:
0.015
0.105
0.15
We clearly see that 0.015 is the smallest, followed by 10.5% (or 0.105), and the largest is 3/20 (or 0.15). Therefore, ordered from least to greatest: 0.015, 10.5%, 3/20.
