A reciprocal is the number that when multiplied with the original number will give you 1. 1/19 times 19 gives you 1.
Division by a number is the same as multiplication by its reciprocal. That is, n / a = n * (1/a) and as you should know, (1/a) is the reciprocal of a.
To get the reciprocal of a fraction, exchange the numerator and denominator.
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.
1/19 would be the reciprocal of 19. It's just the opposite.
21/9 = 19/9 so its reciprocal is 9/1921/9 = 19/9 so its reciprocal is 9/1921/9 = 19/9 so its reciprocal is 9/1921/9 = 19/9 so its reciprocal is 9/19
The Reciprocal is 19 over 56 * 1
Division is the inverse operation to multiplication. Division by a number (other than zero) is the same as multiplication by its reciprocal.
Because division by a number (the second fraction) is the same as multiplication by its reciprocal.
The multiplication inverse of a number is the reciprocal of that number. In this case, the multiplication inverse of 0.32 is 1/0.32, which simplifies to 3.125. This is because multiplying a number by its reciprocal always results in 1, as in the case of 0.32 * 3.125 = 1.
1/19 is.
The reciprocal property of multiplication says that (a/b) times (b/a) equals 1.
Because multiplication and division are inverse operations. And the reciprocal of a number is its multiplicative inverse.
