Division isn't a matter of complicated multiplication and crap but rather how many times something fits into something else hence the reason for .5/.05 equaling 10 like most others said. Think of it in another way: 1/20 (.05) multiplied by 10 = 1/2 (.5). And no!!!!! you cannot divide by 0. And even if you could the answer would not be 0 due to the fact that 0 does not fit into a number such as 10, 0 times. In theory it can, however, go into a number infinite times since 0 has no limits. 0 can, however, be divided by 0 and in theory the answer would be considered 1, of course. The answer being zero is simply a statement to its impossibility and the fact that if you multiply something by 0 it will be 0. If you divide by infinite then technically the answer is infinite because there is no limit to numbers. Also I disagree that using decimals is better. Would you rather look at a number that says .01 or a number that says 1/100. It may be easier to use decimals in the sense that you don't have to find a common factor, but fractions are more accurate because you usually round up decimals when converted from fractions. Decimals are better when you have a calculator, but fractions are easier when you have to do math with your head. For example .1 multiplied by .1 will cause major confusion in where the decimal point is where as 1/10 multiplied by 1/10 is simple as that because it uses familiar numbers and all you have to do is multiply the numerator by the numerator and the denominator by the denominator. This is all really my preference and my way of understanding, but I find it simpler this way. I don't mean to stomp all over I'm just showing how I am able to to have a perfect A in math. I can't say that I have taken AP Chemistry yet, but I'm not even going to. I agree that decimals are probably best in science, but anything else its better to use fractions because they pretty much summarize a decimal. Instead of taking AP Chem I'm actually going to take Anatomy and Physiology which is supposedly the hardest non-AP science class ans really the only difference between AP and regular is that AP gets you extra credits for college and it focuses all on the AP test a month before school ends.
