Step-by-step explanation:
7 over 8 can be seen as

or 7÷8.
This is what this question will look like on a calculator.

As you can see, you will only get 0.875 so your answer will be terminating.
Terminating = Answer Stops
ex.) 0.784 or 0.25
Repeating = Answer Repeats
ex.) 0.5555... or 1.33...
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
I may not know many but here it goes...

The answer is A. If there are 30 people and 14 are boys, that means there are 16 girls. So you put 16/14 and simplify so that would be 8/7.
