Step-by-step explanation:
1 2/3*9=15
His mistake was in multiplying the 3 with the 12. He should have divided it from the 12 because that would have gotten rid of the 3 with the variable. It would also lead to the correct answer, which is b=4

B. 14-9/6-3 = 5/3
C. 9-4/19-0 = 5/19
D. 10-7/10-5 = 3/5
