To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second one.

Answer: -a/b is a fraction, its reciprocal is -b/a Why: Let's look at what reciprocal does. Take a fraction like 1/3 and its reciprocal is 3 . That is 1/ (1/3) and if we multiply the number by its reciprocal we get one. So now take -1/3. The question is whether the reciprocal is 3 or -3. If we multiply - 1/3 by 3 we have -1 and if we multiply it by -3 we have 1. The reciprocal of a positive or negative fraction is obtained by switching its numerator and denominator, the sign of the new fraction remains the same. So the answer is -3 and just as with positive fractions, we have the number multiplied by its reciprocal is 1

When you multiply a nonzero fraction by its reciprocal you get 1. Take this example.Lets say you have a fraction called (a/b). The reciprocal of that fraction would be (b/a). If you multiply the two you'd get (a/b)*(b/a)=(ab/ab). Anything divided by itself is 1.

You multiply the negative number by the reciprocal of the fraction.

Yes. One method for dividing fractions is to multiply the numerator fraction by the reciprocal of the denominator fraction.

Dividing by a fraction is equivalent to multiplying by its reciprocal. A reciprocal fraction is effectively "turning it upside-down". So, to divide by a faction, you should do as stated; turn the fraction upside-down and multiply.

Reciprocal just means that you flip the fraction... your fraction is -p/4 the reciprocal is 4/-p the reciprocal is extremely important when dividing fractions. because when you divide fractions you have to take the reciprocal of the bottom fraction and then multiply it to your top fraction to get your answer.

One simple way is to flip the second fraction over (use its reciprocal) and multiply them.

the reciprocal of a number is 1 divided by the number. if you want to find the reciprocal of a fraction you would need to swap the fraction numbers around and then multiply by 1. and then divide the answer.It is 1 divided by the number.

"Of" usually means that you have to multiply, not divide. To multiply, you don't take the reciprocal.

That is correct. To divide by a half, you are actually multiplying by two. ■
