Which list shows the numbers in order from least to greatest?

B. 1.4, 1.38, 137
C. 1.4, 137, 1.38
D. 1.38, 1.4, 137
E. 137, 1.38, 1.4

Answer :

1. 1.38
2. 1.4
3. 137

1 comes first because 38 is less than 40 and number 2 is 1.40 so 1.38 is less than 1.40 and 137 is the largest number because it has no decimals.
Before giving you the answer, let's talk about decimals for a moment.

Which is greater? 1.4 or 1.38?

Think of it this way: add a zero to the end of 4. It is technically there, just understood, so we can add it in.
This becomes 1.40
Is 40 greater than 38?
Yup!

ANSWER: 1.38, 1.4, 137
