When you divide one fraction and another why do you have to turn it into a reciprocal?
To divide by a fraction, you multiply by its reciprocal. This is related to the facts that (1) division is the opposite of multiplication, and (2) a reciprocal is the multiplicative "opposite" of a number.
How do you use a reciprical to divide a number by a fraction?
Division is multiply by the reciprocal.
What is a reciprocal in math fractions?
A reciprocal is when you take the second fraction in a division problem and flip it Then change the sign to multiply. THIS ONLY WORKS WHEN YOU ARE DIVIDING FRACTIONS!
When do you take the reciprocal of a fraction?
You take the reciprocal of a fraction when you want to invert the numerator and the denominator. The reciprocal of a fraction is found by flipping the fraction upside down. For example, the reciprocal of 2/3 is 3/2.
What ia a reciprocal fraction?
The reciprocal of the fraction is simply the fraction raised to the -1 power. Simply "flip the fraction upside down" to find the reciprocal. e.g. 3/23 has a reciprocal of 23/3.

How is multiplication and division of fractions alike and different?
Division by a fraction is the same as multiplication by its reciprocal. The reciprocal of a number x is 1 over x. So the reciprocal of 2/5, for example, is 5/2.
How is the multiplication of fractions and division of fractioms alike and different?
Division is the multiplication by the reciprocal or multiplicative inverse. In simpler language, to divide by a fraction change the division sign to multiplication and flip the fraction.
How are fractions related to division?
Fractions are related to division because the top of the fraction is the numerator or the dividend of the fraction and the bottom of the fraction is the denominator or the divisor of the fraction.
