3 3/15 + 4 2/5
First, find the common denominator. That's the number that is evenly divisible by both denominators.
In this example, the common denominator is 15.
15/5 = 3
3 * 2 = 6
2/5 = 6/15
3 3/15 + 4 6/15 = 7 9/15 = 7 3/5
I have a hard time understanding the process of adding fractions with unlike denominators, and I usually will go on Khan Academy to look at tutorials and walkthroughs but I can't do that during school (only when I'm doing my homework @ home). Can somebody put it simply?
Example from my homework:
3 3/15 + 4 2/5
