We are given what is called a fraction.
A fraction has two things: a numerator and a denominator.
A fraction is written like this:
[tex] \frac{1}{2} [/tex]
The numerator is on top, and the denominator is on bottom.
In this case, 1 is the numerator and 2 is the denominator.
In your question, instead of 1, we have "84 x 78" for the numerator and "7" for the denominator.
Don't panic!
We can use a calculator here(or if you're really up for a challenge do it by hand) to calculate 84 multiplied by 78 first.
Then, you divide the answer of "84 x 78", 6552, by 7.
Use a calculator if you must(or challenge yourself!).
The answer is 936.
