Put these in order starting from the smallest.
The first one is done for you.
0.72
0.799

Step-by-step explanation:

You'll find it easier to do this problem if you'd first rewrite the numbers so that they're all in the same numerical format:

A:  3/4 = 0.75

B:  0.72 = 0.72

C:  4/5 = 0.80

D:  0.799 = 0.799

E:   9/10 = 0.90

Now it's easy to see that B:  0.72 is the smallest of the 5 numbers and that 0.90 is the largest.

Arranged in ascending order, we have 0.72, 0.75, 0.799, 0.80, 0.90
