arraange the following numbers in order from least to greatest:2 1/4, 0.6, 2.75, 40%, 7/5

The easiest way is to convert the fractions to decimals.

2 1/4 = 2.25
40% = 0.4
7/5 = 1.4

I'll be glad to check your answer.

To arrange the numbers from least to greatest, let's first convert them all into a common form.

1. For 2 1/4, we can convert it into a decimal by adding 1/4 to 2:
2 1/4 = 2 + 1/4 = 8/4 + 1/4 = 9/4 = 2.25

2. For 40%, we need to convert it to a decimal as well. To do that, divide it by 100:
40% = 40/100 = 0.4

3. Let's leave 0.6 as it is since it is already in decimal form.

4. For 7/5, divide 7 by 5 to get the decimal equivalent:
7/5 = 7 ÷ 5 = 1.4

Now that we have all the numbers in decimal form, we can arrange them from least to greatest:

0.4, 0.6, 1.4, 2.25, 2.75

So, when arranged from least to greatest, the numbers are: 0.4, 0.6, 1.4, 2.25, 2.75.
