Nita studied 4 1/3 hours on Saturday and 5 1/4 hours on Sunday. How many hours did she spend studying?

9 7/12 hours

Step-by-step explanation: To solve this problem we will simply add 4 1/3 to 5 1/4. first we will need to make the denominators the same. The denominator that will work for both numbers is 12.

So, multiply the denominator and numerator in 4 1/3 by 4 to get 4 4/12 and multiply the denominator and numerator in 5 1/4 by 3 to get 5 3/12.

Now simply add the two hours together.

4 4/12 + 5 3/12 = 9 7/12

So Nita spend 9 7/12 hours studying.
