x + 7/4 = 17/8 ; {1/8 , 3/8 , 5/8 , 7/8}
The part I'm having trouble understanding are ; and the commas between the fractions in the parentheses.
Can someone help?

The stuff in parenthesis are the choices you have for answers....the correct answer is 3/8
To further explain:
Since one side of your math problem is in fourths (7/4) and the other side is in eighths (17/8)...it is easier to work this problem if both sides are in eighths....
take 7/4 and mutiply it by 2/2 so you can now make it 14/8
then you know that "x" is going to be "something over 8"
Using the top numbers 3 + 14 = 17.....
You already know the bottom number is 8....
So your answer has to be 3/8

The french brackets or braces { } are typically used to identify a set of numbers:
{a,b,c} means the set consisting of a, b, and c.
The semicolon ; is typically used to indicate "given".
So, in English, you should read it like this:
Solve for x in the equation x+7/4=17/8 given the set of numbers 1/8, 3/8, 5/8, 7/8.
The answer being, of course, 3/8. But your questions was really about the symbolism, I'm sure. You might want to bookmark the following website, if you have any other questions about math symbolism:

x=17/8-14/8=3/8

the answer is x = 3/8
solution is simple
7/4 = 14/8
therefore 14/8 + 3/8 = 17/8
;{ } = answers to chose from and the commas seperate them.
all maths books should come with a translator

they are probably answer choices.
x + 7/4 = 17/8
x = 17/8 - 7/4
x = 17/8 - 7/4 * 2/2
x = 17/8 - 14/8
x = 3/8

The fractions in the parentheses are the potential answers..
