What is two-thirds plus three-fourths?

Answer 1

You solve this question by finding a common denominator. In this case, what is the smallest number both 3 (on the bottom of 2/3) and 4 (on the bottom of 3/4) go into to. The answer is 12. 3 goes into 12 4 times, so you multiple the numerator of 2/3 which is 2 by 4 and also the denominator, which is 3 by 4. You end up with 8/12. Now you repeat the process for the other one. 4 goes into 12 3 times (notice 4 is the denominator of 3/4). Now multiple the numerator and denominator by 3 and you will get 9/12.

Now that you have a common denominator of 12 you can add the top number together and put them over 12.

So, 8/12 + 9/12 = 17/12

I hope this helped.
