1/2 9/10 4/5 which on e go first to put in lowest number on the left

Since 1/2 = .5, 4/5 = .8, and 9/10 = .9. I found these out by dividing the numerator by the denominator. Now that we have them in decimal form, we can order them from least to greatest: 1/2, 4/5, and 9/10. You can also figure out how to order them from least to greatest by finding a common denominator, like 10. 1/2 = 5/10, 4/5 = 8/10, and 9/10 stays the same. (Looking back to the first example, if you don’t have a calculator you can do it this way to find the decimal forms) then you can order them from least to greatest!

Hope one of these meathods helped you, and happy holidays!

1/2 = 5/10
4/5 = 8/10

Least to Greatest
5/10, 8/10, 9/10
