"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.

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.
The two imaginary lines that divide the Earth into hemispheres are the Equator, which divides the Earth into the Northern and Southern Hemispheres, and the Prime Meridian, which divides the Earth into the Eastern and Western Hemispheres.
To find what divides what times what equals 0.36, we can express 0.36 as a product of two numbers. One way to do this is to factorize 0.36 into its prime factors, which are 2^2 * 3^2 * 0.01. Therefore, the numbers that divide to give 0.36 are 0.6 and 0.6, as 0.6 * 0.6 = 0.36.
