Answer:

What is Multiplicative Inverse?

The word meaning of ‘inverse’ is something opposite in effect. So, the multiplicative inverse of a number is a number that nullifies the impact of the number to identity 1. Thus the multiplicative inverse of a number is a number by which the multiplication results in 1.

That is, number b is the multiplicative inverse of the number a, if a × b = 1.

For example: Here is a group of 7 dimes. o make them into groups of 1 each, we need to divide it by 7. The division is the reverse process of multiplication. Dividing by a number is equivalent to multiplying by the reciprocal of the number.

Thus, 7 ÷7=7 × 1⁄7 =1.

Here, 1⁄7 is called the multiplicative inverse of 7. Similarly, the multiplicative inverse of 13 is 1⁄13.

Another word for multiplicative inverse is ‘reciprocal’. It comes from the Latin word ‘reciprocus’ which means returning.

Multiplicative inverse of a natural number

In the given image to make the unit groups of 8 stars, we need to divide it by 8.

8 ÷8=8 × 18=1

Thus, the multiplicative inverse of 8 is 1⁄8.

In general, if a is a natural number, the multiplicative inverse or reciprocal of a is 1⁄a.

Multiplicative inverse of a unit fraction

To make a unit fraction, say 1⁄4 to 1, we need to add it 4 times. Or in other words, multiply 1⁄4 by 4. Thus, the multiplicative inverse of 1⁄4 is 4.

In general, the multiplicative inverse or reciprocal of unit fraction 1⁄x is x.

Multiplicative inverse of a fraction

By what number should we multiply the fraction 3⁄4 to get 1?

3⁄4× ?=1

By the properties of equality, if we multiply or divide both sides of an equation by the same number the equation remains true. So, by multiplying the equation by 4 and dividing it by 3 on both sides gives us

3⁄4 × ? × 4 ÷3 =1×4 ÷3

3⁄4 × ? × 4⁄3= 4⁄3

Canceling the common terms:

1× ? = 4⁄3

Thus, the multiplicative inverse of 3⁄4 is 4⁄3.

The multiplicative inverse or reciprocal of a fraction a⁄b is b⁄a.
