Carlos sold 18 tickets because
The answer is 18 but let me explain why that is. First of all let's assume (because it's true) that 3/4 is the same as saying 3/4 of one which is the same as saying 3/4 x 1 the answer then to that is 3/4 (go figure) so then using this logic we can say that 3/4 of 24 is the same as 3/4 x 24, which is an easy expression to evaluate if you have a calculator, but what if you don't, then what? Then you have to evaluate, 3/4 x 24 is the same as saying 3 x 24 = 72, then taking 72 and dividing by 4 which will give you 18, the answer. So I hope you can see the connection here, again if we have 3/4 of one we know that's the same as 3/4 x 1 which is equal to 1 x 3 = 3 then divided by 4 which is 3 divided by 4 which is the same as, you guessed, 3/4. Hope that helps, good luck with math in the future.
