The answer in simplest form would be: 3/4 First, think of a common denominator: 12. Multiply 1/4 by 3/3 (you need to do the same to top and bottom): 1/4x3/3=3/12 Multiply 3/6 by 2/2: 3/6x2/2=6/12 Then you just add the numerators together: 3/12+6/12 (3+6=9) You don't need to add the denominators. So the answer is 9/12. But you can simplify 9/12 to 3/4. Hope this helps! :D
