• What if you have to divide by 15 or 30?
• In the first example, Sal uses the partitive method of division in this video (opposed to the measurement method of division). Is there a way to visually express the partitive method of division for complex fractions, (a/b)/(c/d), without resorting to visually expressing fraction multiplication after flipping the divisor? Thanks!
• I really learned stuff on khan academy. i think it is the most best website ever
• why is there no remainders
• That is because the number is exactly divisble
• I know how important division is, but what are some careers that involve division?
• basicly I would say I don't know
• My child Marlee asked if you could do some more advanced division problems? Ex= 34-:- 7=!
• Not that advanced, but the solution would either be a fraction or a decimal.
34/7=4.8571
• The top right smilie face only has one eye.
• hey hows it going and yes it is missing!! lol
• It helps with many things, including certain formulas in physics and chemistry. It will also help you with dividing quantities, simplifying radicals, and other math-related things. There are many more things that division helps with, so you should definitely learn your division facts, as well as learn how to do long division.
