To get the reciprocal of a fraction, exchange the numerator and denominator.
Because division by a number (the second fraction) is the same as multiplication by its reciprocal.
When dividing by a fraction, the answer is obtained by multiplying by the 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.
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.
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.
It is because division by a non-zero number is the inverse operation of multiplication of multiplication.
The multiplicative inverse of a quantity may, when the operation of multiplication is commutative, be called its reciprocal. Thus the reciprocal of 72 is 1/72.
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.
You find the reciprocal of the second fraction- flip it over. And then you multiply the two fractions.So (a/b) / (c/d) = (a/b) * (d/c)You find the reciprocal of the second fraction- flip it over. And then you multiply the two fractions.So (a/b) / (c/d) = (a/b) * (d/c)You find the reciprocal of the second fraction- flip it over. And then you multiply the two fractions.So (a/b) / (c/d) = (a/b) * (d/c)You find the reciprocal of the second fraction- flip it over. And then you multiply the two fractions.So (a/b) / (c/d) = (a/b) * (d/c)
1/3. The fraction for 3 is 3/1, and to find a reciprocal, you have to flip the fraction.
To divide two fractions, multiply the first by the reciprocal of the second.
Number x Reciprocal = 1 Therefore Reciprocal = 1/Number
