"Dose" is a measured portion of a medicine. I am not aware of any persents - percents, even - that have measured quantities of medication!
Furthermore, without brackets (parentheses) the question is ambiguous:
3/(2/5) = 7.5 = 750 per cent
(3/2)/5 = 3/10 = 0.3 = 30 per cent
The numbers 2, 43, and 97 divide into 8342.

It is not. 2/10 = 0.2

Any number raised to the power of zero equals 1. For example, start out with 2^3 = 8. Then divide by 2 and get 2^2=4. Divide by 2 again: 2^1=2. Divide by two again: 2^0=1.
The numbers 2, 43, and 97 divide into 8342.
2 divides exactly 18 times into 36, there is no remainder.
identical twins, if the egg divides in 2; identical triplets, if it divides into 3, and so on...

No it equals 316.5
It is not. 2/10 = 0.2
These four numbers divide evenly into 514: 1 2 257 and 514.

Any number raised to the power of zero equals 1. For example, start out with 2^3 = 8. Then divide by 2 and get 2^2=4. Divide by 2 again: 2^1=2. Divide by two again: 2^0=1.
634 divided by 2 equals 317.
