What is two divided by three fifths?
(2)/(3/5) correct? Well let's remember the laws of multiplying and dividing fractions. To divide a fraction you take the reciprocal and multiply. Let's use this here. Also remember that a whole number is the same as that number over 1 to make it a fraction. For instance in this case we will say 2 = 2/1 making the actual problem (2/1)/(3/5) Now we take the reciprocal of 3/5 (which is 5/3 because (3/5) * (5/3) =1) and multiply by it making the problem (2/1) x (5/3) Now multiply the top times the top and the bottom times the bottom and you get (2*5)/(1*3) =10/3 There's the solution 10/3

Why must you multiply by the reciprocal when dividing fractions?
I dont kno. good questionFrom Kevin: I have the problem in Math class today in school. And this is what I came out with:For just a moment, don't think 2 numbers as fractions, think of them as x and y. X divided by YWhen X divided by Y (or "Y over 1"), you can write it as : X times "1 over Y". Thus you get a statement: "When a number was divided by another number, the answer shall equal to the first number times the reciprocal of the second number."Same statement goes with fraction. Understand?
Does pi times any number equal an irrational number?
Since pi is irrational, its product with any other number is also irrational. The only exception is a multiple of its own reciprocal.
