D'oh, you modified it after I answered the question. The answer is stiill the same. e) 114/19

The fractions have a common denominator already so you just add it through.
they're fractions. not division questions (BEDMAS)

The answer is B) 26/5

Originally, you had the same denominator. In that case, I was right to have 114/19. Since it was modified to have different denominators, you need to solve for common denominators first. 95 is common to both fractions.

The answer was actually 494/95, but that can be reduced to 26/5.

Yeah just take the common demoninator which in this case is 95. Since 95 divided by 19 equals 5. You have to mulitply the top number by 5 which is where you get 475. so you have 475/95 which reduced is 25/5.

I've seemed to have done something wrong. I'm sure that is how you add two fractions.

the answer is D) 210.

210 is the lowest common multiple of 42 and 70...

the answer is not 14 (42 and 70 are multiples of 14, 14 is not a multiple of 42 and 70)
this link should help.
