Grade 5-Unit 5-Lesson 03 (1)

There is no right or wrong answer, but be ready to explain your reasoning about why you think it does not belong.

Different Ways to Express a Decimal

Which one doesn't belong?

1. 26 ÷ 100
2. 0.26
3. 26 ✕ 0.001
4. (2 ✕ 0.1) + (6 ✕ 0.01)

Which One Doesn’t Belong?

You may have noticed that one of the answers, (2 ✕ 0.1) + (6 ✕ 0.01), is written in expanded form.
