Lest to Greatest.

2/3, 0.6, 0.66

I know 2/3 = .6 reapeating.

so would it be 0.6,0.66, 2/3?

You've got it! :-)

since you can convert decimals into fractions and if it is a repeating decimal you put it under a 9 so it would 6/9

To arrange the numbers from least to greatest, you need to compare their values. Let's break it down step by step:

1. Start by comparing the decimal values of the numbers: 0.6, 0.66.
- Since 0.66 is greater than 0.6, we place 0.66 after 0.6.
- The current order is: 0.6, 0.66.

2. Now compare the remaining fraction, which is 2/3, with the decimal numbers.
- To convert 2/3 to a decimal, divide the numerator (2) by the denominator (3).
- The result is 0.666666... which repeats infinitely.
- Hence, 2/3 is greater than 0.66.
- The final order is: 0.6, 0.66, 2/3.

Therefore, the numbers arranged from least to greatest are: 0.6, 0.66, 2/3.
