Addition
Step-by-step explanation:
Answer:
2/4 x 7/10 = 14/40, or 7/20.
5/6 x 3/4 = 15/24, or 5/8
3/4 x 2/3 = 6/12, or 1/2
3/10 x 4/5 = 12/50, or 6/25
i think you can finish the rest, all you have to do is multiply the numerator and the numerator, and the denominator and the denominator.
numerator = number on the top
denominator = number on the bottom
then put the two results:
[numerator x numerator]

[denominator x denominator]

Answer:
B!
Step-by-step explanation:
we know that (x-5) and (y-6) must add up to 129 because 180-51 is 129
now let's plug in the values to see
51-5= 66 63-6 = 57
57+66 is 123, not this one, let's repeat the same step
77-5 is 72, 63-6 is 57, these added is 129
