Solve and show working for 6 4/6 + 4 2/4=

First you need to find a common denominator. To do that, you have to look at the denominators of the two fractions. They are 6 and 4. The closest number that they can both go into is 12. 6x2=12, 4x3=12. Then, what you multiplied the denominator by to get the number 12, you have to multiply the numerator, too.
So, it would be 8/12 + 6/12. That is 14/12, or 1 1/6. Then you add that to the whole numbers, 6 and 4, which is 10. 10 + 1 1/6= 11 1/6.

The answer is 11 1/6

So sorry that took so long

6 4/6 + 4 2/4 is equal to 11 1/6.
First, I added 6 + 4 to get 10.
Putting the first step to the side for now, I know that 2/4 is equal to 1/2, which is also equal to 3/6.
Then I added 4/6 + 3/6 to get 1 1/6.
Adding 10 + 1 1/6, I got 11 1/6.
Sorry if this isn't very clear, math isn't my best subject.
