To order the numbers from greatest to least, we first evaluate the absolute values and then compare them.
The numbers are:
- 20
- -22
- |−45| which is 45
- |−49| which is 49
Now we list them in order from greatest to least:
- |−49| = 49
- |−45| = 45
- 20
- -22
So the order from greatest to least is:
49, 45, 20, -22
Thus the final answer is:
□ 49
□ 45
□ 20
□ -22
