How would you order 7/12, 0.75, and 5/6 from least to greatest?

Least to greatest: 7/12, 0.75, 5/6

Explanation:
Leave 7/12.
5/6 is equivalent to 10/12 if you multiply the numerator and denominator by 2.
0.75 is equal to 75/100, which is equal to 3/4 if you divide numerator and denominator by 25. 3/4 is equal to 9/12 if you multiply by 3.
You can look at the three numbers as 7/12, 10/12, and 9/12.
