**What is the multiplicative inverse of C D?**

About “Multiplicative inverses” Multiplicative inverses : For every rational number a/b, a ≠ 0, there exists a rational number c/d such that (a/b) x (c/d) = 1. Then c/d is called the multiplicative inverse of (a/b).

## What is the formula of multiplicative inverse?

In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a.

### Does 0 have a multiplicative inverse?

The short answer is that 0 has no multiplicative inverse, and any attempt to define a real number as the multiplicative inverse of 0 would result in the contradiction 0 = 1.

**What’s the inverse of 1?**

**What is meant by modular inverse of a number?**

In mathematics, particularly in the area of number theory, a modular multiplicative inverse of an integer a is an integer x such that the product ax is congruent to 1 with respect to the modulus m. In the standard notation of modular arithmetic this congruence is written as ≡ (),

**What is the inverse property of multiplication?**

The inverse property of multiplication states that a number multiplied by its reciprocal equals 1. The reciprocal of 1/2 is 2/1, or 2.

## What is the inverse operation of multiply by?

What is the Inverse of Multiplication? The inverse of multiplication is division . If you multiply by a given number and then divide by the same number, you will arrive at the same number you started with. Division has the opposite effect to multiplication. For example here is 3 × 2 = 6. We started with the number 3. We multiplied it by 2 to increase 3 to 6. An inverse operation must be used to return from 6 to 3. The opposite of multiplying by 2 is to divide by 2. We divide 6 by 2 to return
