Answer:
D
Step-by-step explanation:
10!=3628800
10-3=7
7!=5040
3628800/5040=720
5.30 and 5.3 are equivalent to 5.300.
You see, if there is a zero at the end of each decimals, that is nothing.
Zeroes or nothing.
But if it were to be a number, for example:
5.3003, it would be different.
5.3000000000000000000000000000000000
is the same thing to 5.3
Ask me if you don't understand.
