The answer is: [B]: 7/9 .
_______________________________________
Step-by-step explanation:
________________________________________________________
Method 1:
________________________________________________________
7/12 ÷ 3/4 = 7/12 * 4/3 ; The "4" cancels to a "1";
and the "12" cancels to a "3";
(since "12÷4 =3"; and "4÷4 =1" ;
___________________________________________________
7/12 * 4/3 = 7/3 * 1/3 = 7/9 ; which is: Answer choice: [B].
_____________________________________________________
Method 2:
______________________________________________________
7/12 ÷ 3/4 = 7/12 * 4/3 = (7*4) / (12*3) = 28/36; which can be reduced by dividing EACH side by "4":
_____________________________________________________
28/36 = (28÷4) / (36÷4) = 7/9 ; which is: Answer choice: [B].

It would be: 7/12 / 3/4
We can re-write it as: 7/12 * 4/3
= 7/3 * 1/3
= 7/9

In short, Your Answer would be Option B

Hope this helps!
