Answer:
8 and 7/10
Step-by-step explanation:
When adding mixed numbers, here's a method I use. I first pretend that that whole number part of the fraction doesn't exist, and that we'll deal with it later. So now we just have 2/5 and 3/10. Next, I make the denominators the same. 10 divided by 5 is 2, so multiply both the numerator and the denominator of 2/5 by 2. Now we have 4/10 + 3/10. This looks pretty easy now; since 4 + 3 is 7, our fraction is 7/10. Now throw those whole numbers back into the mix, (6 and 2,) and add them to get 8. Our final answer is 8 and 7/10.
