How do you divide a reciprocal fraction?
multiply by the reciprocal
Is the reciprocal of an improper fraction sometimes always or never a proper fraction?
For a fraction A/B, the fraction is improper if A > B. The reciprocal is B/A. So now A is the denominator, and B is the numerator, and B < A, so the reciprocal is a proper fraction. The answer would be always.
Why do you take the reciprocal of the second fraction when dividing?
Because division by a number (the second fraction) is the same as multiplication by its reciprocal.
What is a resiprical?
To get the reciprocal of a fraction, just the fraction. For example, the reciprocal of 3/4 is 4/3. The reciprocal of 1/5 is 5/1 or just plain 5.
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
