Order from least to greatest 0.5, 1/5, 0.35, 12/25, 4/5

First put all the fractions in decimal form. So now we have 0.5, 0.35, 0.2 for 1/5, 0.48 for 12/25, and 0.8 for 4/5. This makes it easier to order. So now we can see the answer is  0.2, 0.35, 0.48, 0.5, and 0.8. Then you have to go back and put the fractions in, so the order is  1/5, 0.35, 12/25, 0.5, and 4/5.
