Answer:
C. 2/3
Explanation:
To solve this, we should come up with a common denominator first.
The least common denominator (LCD) of the four fractions would be 120.
So, first multiply each fraction's denominator to get 120, and multiply the numerator by the same amount.
ex. 3/4
4 x 30 = 120
3 x 30 = 90
We get 90/120.
After doing this with each fraction, we get;
13/15 = 104/120
7/8 = 105/120
2/3 = 80/120
3/4 = 90/120
Now, it is easier to see which fraction has the least value (or the one that is the smallest. Your answer is 2/3, since 80/120 is the smallest out of the four.
