Answer:its A. 3/7 because it would be 12:28 so you'd simplify it.
Step-by-step explanation:
12/28=3/7
Im gonna assume you mean 6 - (1/3)x = -1. Your notation is not super clear. If so, solution is as follows:
6 - (1/3)x = -1 [subtract 6 from both sides]
-(1/3)x = -7 [multiply both sides by -3]
x = 21
the answer that is equal to 1/4 is 2/8 3/12 and 4/16
