order 3/10 from least to greastest

To order 3/10 from least to greatest, you can compare it with other numbers. Let's consider a few fractions to compare it with:

1/2, 1/3, 2/5, and 1/4

Now, to compare fractions, it is helpful to have a common denominator. In this case, we can find a common denominator by multiplying the denominators together: 2 * 3 * 5 * 4 = 120.

Now, let's convert all the fractions to have the same denominator of 120:

3/10 = 36/120
1/2 = 60/120
1/3 = 40/120
2/5 = 48/120
1/4 = 30/120

Now, we can order them from least to greatest:

36/120 < 30/120 < 40/120 < 48/120 < 60/120

Simplifying these fractions, we have:

3/10 < 1/4 < 1/3 < 2/5 < 1/2

So, when ordered from least to greatest, we have: 3/10 < 1/4 < 1/3 < 2/5 < 1/2.
