Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
Answer:
There is really no answer to this because this is the furtherest you can go to simplify this expression. I can help solve it if you give me more information, or you tell me what the value of a and b is so I can solve it.
Thanks!
You first need to convert the fractions so they are both eighths.
1 3/4 = 1 6/8
Then you simply need to add:
1 6/7 + 3 3/8 = 4 9/8 = 5 1/8
Your answer is 5 1/8.
(7,2) is the answer.
There you go.
