how can I do this fraction
First turn the fraction into common denominators. Then add them.1/3 = 4/121/4 = 3/124+3 = 7=7/12
You need a common denominater so multiply 3 by 4 and 4 by 3.You will also need to multiple 1 by 4 and 3.Then you add you numerators straight across.So the answer should be 7/12.
