HELP ME I CAN’T FIGURE IT OUT!!

B is right

Step-by-step explanation:

To add the fractions you need common denominators (the number at the bottom of the fraction) so the 12 is the common denominator. since the denominator on the bottom which is 4 turns into 12, you divide those and get 3. Once you get 3 you multiply it by the top number of 4 which is 9. Same with the next fraction which equals 10/12. Lastly, you add the top numbers together only since the bottom is already simplified. And.. 19/12 equals 1 7/12 because theres is 12/12 in 19/12 and leaves 7 extra which is 1 7/12

3/4=9/12.      5/6 10/12

Step-by-step explanation:

ok this is easy so when it puts you 3/4 = /12 and 5/6 = /12

all you have to do is

multiply 4 times 3 for the bottom to get 12 and multiply 3 on top to

so 3/4 = 9/12

and for 5/6 = /12 you have to multiply 6 times 2 to get 12 so you multiply 2 on top as well so 5/6 = 10/12
