Answer:
7.77, 7.773, 7 9/11, 157/20
Explanation:
First, convert any fractions to decimals to make it a bit easier to order.
7.773, 157/20, 7.77, 7 9/11
- 157/20 = 7.85
- 7 9/11 => 86/11 => 7.82
Now we have:
7.773, 7.85, 7.77, 7.82
Order from least to greatest:
7.77, 7.773, 7.82, 7.85
Rewrite using the original numbers in the question:
7.77, 7.773, 7 9/11, 157/20
Hope this helps!
