For simplicity sake, let's call Train A "A" and Train B "B".
A + B = 192
A > B
A - B = 120
192 ÷ 2 = 96
96 ± 120 ÷ 2 = 96 ± 60 = 156, 36
Train A weighs 156 tons and Train B weighs 36 tons :)

Answer:
I believe 10
Step-by-step explanation:
the reason I believe it is 10 is because that is the main mathematical explanation for this equation
The no equivalent answer is C.
Reasoning:
To find the answer you have to multiply 9 x 5/6. Because 9 is a whole number, if we put it over 1 it makes it easier to multiply.
9/1 x 5/6 is 45/6.
Now that we have this, we need to find which answers are correct.
If we change 45/6 into a mixed number, we have to do 45 divided by 6. 45 divided by 6 is 7. 6 x 7= 42. 45-42=3 so the mixed number would be 7 3/6. 3/6 is equal to 1/2 so it can also be 7 1/2. This means A. Is correct.
For the next two multiple choice possible answers, they simplified 45/6. Both have a denominator (bottom of the fraction) of 2. This means we need to divide by a number that will make the denominator 2
45/6 divided by 3/3 will get 15/2. This means B. Is also correct.
Because A and B are correct, this means that C. Is not an equivalent answer.
