Problems 5, 7A, and 7C are the only ones with correct answers.
But for 1 - 6, you're also supposed to color in the same amount of the big square,
and for 7, you're also supposed to mark a dot on the number line. You haven't
done any of these things.
All of these problems are just changing a fraction to another fraction that's
equivalent but has a different denominator. Whatever the old denominator
was multiplied by to get the new one, the old numerator also has to be
multiplied by the same thing. If you don't do that, then you've changed
the value of the fraction.
You have some more work to do.
As there are no parenthesis, Follow PEMDAS and go from left to right

Step-by-step explanation:
There would be 5184 ways in which each subject books can be selected.
<u>Explanation:</u>
Number of geography books = 5
Number of chemistry books = 4
Number of Science books = 7
Different ways of selecting geography books = 5!
= 5 X 4 X 3 X 2 X 1
= 120
Different ways of selecting chemistry books = 4!
= 4 X 3 X 2 X 1
= 24
Different ways of selecting Science books = 7!
= 7 X 6 X 5 X 4 X 3 X 2 X 1
= 5040
Total different possible ways they can select them = 120 + 24 + 5040
= 5184
