Mrs. Rivera ran 5 1/4 miles and Ms. Carter ran 4 3/4 miles. How many miles did they run in all?

Answer: 10 miles

Step-by-step explanation: Simply add 5 1/4 + 4 3/4 = 10

Easy way to add:

You could first add 5 + 4 = 9

Then, you could add 1/4 + 3/4 = 1

Lastly, add 9 + 1 = 10.

So, Mrs. Rivera and Ms. Carter run 10 miles altogether.

10 miles. 1/4 + 3/4 = 4/4 which is equivalent to 1, so you add 5+4+1 and get 10
