Which ones the greatest 3/4, 2/3, or 7/8

To find the fraction that is the largest, we need to find the decimal form of all the fractions by dividing the numerator (top number) by the denominator (bottom number). In doing this, we find that:

3/4 = 75%

2/3 = 67% (when rounded)

7/8 = 87.5%

So, we find that out of these three fractions, 7/8 is the greatest.
