To add 3/4 and 1/2, you need to find a common denominator. One way to do this is to multiply the denominators together:
3/4 + 1/2 = (3/4)(2/2) + (1/2)(4/4)
This gives:
3/4 + 1/2 = 6/8 + 4/8
Now that the denominators are the same, you can add the numerators:
6/8 + 4/8 = 10/8
The answer can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 2:
10/8 = (10/2)/(8/2) = 5/4
Therefore, 3/4 + 1/2 = 5/4.
