Order the numbers from least to greatest 0.72, 3-4, 71%, 7/10

3-4, 7/10, 71%, 0.72

Step-by-step explanation:

3-4 is definitely the least, because 3-4 = -1, and this is the only negative number.

Next, we put the other three numbers in the same form to compare more easily.

7/10 = 70/100 = 70%

0.72 = 72/100 = 72%

and 71% is already in percent form, so no need to convert it.

Now we have these three percentages, it is easy to compare:

70%, 71%, 72%

Which is 7/10, 71%, 0.72

Adding the negative number mentioned at first, we get

3-4, 7/10, 71%, 0.72
