Put the decimals in order from least to greatest 1.04, 0.9, 0.621, 1.5

0.621, 0.9, 1.04, 1.5

First, look at the ones place, and determine which is greater. (the numbers in the ones place include: 1, 0, 0, and 1. There are two numbers greater than one, and two less than one, so lets look at the numbers that are less than one. Take a look at the tenths place in 0.9 and 0.621. Notice that 9 is greater than 6, so 0.9 is more than 0.621. Now, lets look at the two greater than one. (1.04, 1.5) Look at the tenths place. In 1.04, there is a 0, whereas in 1.5 there is a 5. This means that 1.04 is less than 1.5. So, that said, the numbers listed from least to greatest looks like this: 0.621, 0.9, 1.04, 1.5  :)
