To find the set of three equivalent decimals, we need to look for decimals that have the same value despite different appearances.
Let's analyze each option:
-
1.9, 1.09, 1.009:
- 1.9 = 1.90 (but does not equal 1.09 or 1.009)
-
1.9, 0.19, 0.190:
- 1.9 does not equal 0.19 or 0.190 (the values are different)
-
1.9, 1.90, 1.090:
- 1.9 = 1.90 = 1.090 (all of these are equivalent)
-
1.9, 1.90, 1.900:
- 1.9 = 1.90 = 1.900 (all of these are equivalent)
Both the third and fourth options are sets of equivalent decimals. If you only need to select one set, choose either the third or the fourth option.
For a strict answer to the question and based on common choices often accepted in such cases:
1.9, 1.90, 1.090 is a valid answer as all three are equivalent decimals.
However, 1.9, 1.90, 1.900 is also correct.
If you have to choose one, go with the first one mentioned above.
