So with these two fractions you're gonna have to find the LCD (lowest common denominator) before you start adding them. With 6 and 8, the LCD is 24.
So with the numerator and denominator of

multiply them by 4. It'll look like this

As for

, do the same except multiply by 3. It'll look like this:

.
Now add the new fractions together:

A is the answer
That is a good question but I'm not sure
