Which fraction is greater? 7/8 or 9/10

In order to determine which is bigger, 7/8 or 9/10 there are two different techniques (both provide the same answer).

First, we could find a common denominator for both fractions. Once we have a common denominator, we can compare the numerator for 7/8 and 9/10. If the denominator is the same for both fractions, whichever has a larger numerator is the larger fraction.

Second, we could also divide 7 by 8 and get 0.875. Then we divide 9 by 10 and we get 0.9. This also allows us to see that 9/10 is a larger fraction than 7/8.

The benefit of using a calculator to change the fraction to a decimal (or you could do it by hand) is that it works on fractions that are similar. For example, 4/11 and 5/12.

Either way, the fraction 9/10 is greater than the fraction 7/8.
