To determine which set of decimals is in order from least to greatest, we can compare each number:
-
1.07, 1.7, 1.73
- 1.07 < 1.7 < 1.73 (correct order)
-
1.77, 1.7, 1.07
- 1.7 < 1.07 < 1.77 (not in correct order)
-
1.7, 1.074, 1.07
- 1.07 < 1.074 < 1.7 (not in correct order)
-
1.7, 1.07, 1.007
- 1.007 < 1.07 < 1.7 (not in correct order)
The correct set of decimals in order from least to greatest is: 1.07, 1.7, 1.73.
