Answer:
2
Step-by-step explanation:
If n is the larger integer, n-1 is the smaller. The difference of consecutive integers is 1, so their sum is ...
n +(n -1) = 3(1)
2n = 4 . . . . . . . . . add 1
n = 2 . . . . . . . . . . divide by 2
The larger integer is 2.
You need to divide the top number by the bottom number and you will get your answer
(3ab/b)-(2bc/b)=12/b
3a-2c=12b^-1
(3a-2c)/12=(12b^-1)/12
(3a-2c)/12=b^-1
12/(3a-2c)=b
