Multiplicative inverse of 1/5 is 5
To find the multiplicative inverse of a fraction, we need to find another fraction that when multiplied by the given fraction, the product is equal to 1. In other words, the multiplicative inverse of a fraction is the reciprocal of that fraction.
The multiplicative inverse of 1/5 can be found by flipping the numerator and the denominator. Therefore, the multiplicative inverse of 1/5 is 5/1 or simply 5.
Explanation:
When we multiply a fraction by its multiplicative inverse, the product is always 1. Let's see this with the given fraction 1/5:
1/5 * 5/1 = (1 * 5) / (5 * 1) = 5/5 = 1
As we can see, when we multiply 1/5 by its multiplicative inverse 5, the product is equal to 1.
Other options:
a) 10 is not the multiplicative inverse of 1/5 because 1/5 * 10 = 10/5 = 2, not 1.
b) 3 is not the multiplicative inverse of 1/5 because 1/5 * 3 = 3/5, not 1.
d) None of these is not the correct answer because the multiplicative inverse of 1/5 is indeed 5.
