What is the order for 2/5, 9/10, 1/3, .50, .05 from least to greatest?

2/5 = 0.4

9/10 = 0.9
1/3 = 0.3

Take it from there.

To order the given fractions and decimals from least to greatest, we need to compare them and arrange them in ascending order. Let's go step by step:

1. Fractions:
- 2/5
- 9/10
- 1/3

To compare fractions, we can find a common denominator. In this case, the least common denominator (LCD) is 30. We'll convert each fraction to have a denominator of 30:

- 2/5 = (2/5) * (6/6) = 12/30
- 9/10 = (9/10) * (3/3) = 27/30
- 1/3 = (1/3) * (10/10) = 10/30

Now, we can easily compare the fractions:

- 10/30 < 12/30 < 27/30

2. Decimals:
- .50
- .05

To compare decimals, we can compare them directly:

- .05 < .50

Now that we have ordered the fractions and decimals separately, we can combine them in ascending order:

- .05, 10/30, 12/30, 27/30, .50

Therefore, the order from least to greatest is: .05, 10/30, 12/30, 27/30, .50.

Put these numbers in order from greatest to least 0.9,0.4,3/4
