What is the algorithm for dividing a fraction by a fraction?
Multiply the first fraction by the reciprocal of the second. That is, flip the second fraction over and then multiply the two.
What is the reciprocal of -p over 4?
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.
How can you dvide fractions?
To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second one.
Why do you turn the fraction upside down and multiply?
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.
What happens when you multiply a fraction by its reciprocal?
You end up with 1.
How do you divide a reciprocal fraction?
multiply by the reciprocal
What do you multiply by a fraction to get 1?
The 'flip' (the reciprocal) of the same fraction.
How do you make a fraction disappear?

When multiplying a nonzero fraction by its reciprocal the product is call?
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.

What is the reciprocal of a negative fraction?
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
