How does 7/8 compare to 8/7?

Not sure if this is what you mean, but 7/8 < 8/7

Step-by-step explanation:

In 7/8, the numerator is smaller than the denominator, so the fraction is less than 1.  In 8/7, the numerator is greater than the denominator, so the fraction is greater than 1.  Thus, 8/7 > 7/8.
