Why does dividing fractions involve multiplication?
Dividing fractions invole multiplacation because you can use it too see how many time's a number goes into another answer. And that is why dividing involves multiplacation.
How do you carry out division when the divisor is not an whole number?
It is often useful to convert division into multiplication, by inverting the fraction; dividing by 2/3 is the same as multiplying by 3/2.
Dividing by a fraction will increase the number but multiplying by a fraction will decrease the number?
true
How are multiplying and dividing rational numbers related?
Dividing by a rational number (other than zero) is simply multiplication by its reciprocal.
When dividing x by x and you have exponents on each of the x do you add the exponents or subtract?
When dividing numbers (or variables) subtract the exponents. Remember, an exponent indicates a kind of multiplication, it is the number of times that a number is multiplied by itself. If you are dividing by that same number, then clearly you are multiplying it by itself a fewer number of times. Division is the inverse function of multiplication.
Why do you take the reciprocal of the second fraction when dividing?

Why is dividing by a fraction the same as multiplying by its reciprocal?
Because by definition division , by a non-zero number is the inverse operation to multiplication.

What is one step when multiplying fractions?
Multiplication of fractions is similar to multiplication of whole numbers. Often, multiplication of fractions can be made easier by first performing cancellation. Cancellation involves dividing both a numerator and a denominator by the same number. This is the same as dividing a fraction by one, and so it does not alter the answer. When cancelling, cross out the old terms and write in the new terms.

How do you multiply a fraction and a whole number with a fraction?
Convert the mixed number to an improper fraction and proceed with the multiplication.
