# What’s the inverse of 4?

What’s the inverse of 4? The multiplicative inverse of 4 is 1/4. (One-fourth is 1/4 in written form.)

## What is the inverse of 1 2?

Answer: The multiplicative inverse or reciprocal of 1/2 is 2.

## What is the inverse of 12?

The multiplicative inverse of 12 is 1/12.

## What is the inverse of 3?

The multiplicative inverse of 3 is 1/3.

## What is the multiplicative inverse of 4 7?

i.e, multiplicative inverse of 4/7 is 7/4.

## What is the inverse function of 1 2x?

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x f – 1 ( x ) = 2 x is the inverse of f(x)=12x f ( x ) = 1 2 x .

## What’s the inverse of 2?

The additive inverse of 2 is -2. In general, the additive inverse of a number, x, is -x because of the following: x + (-x) = x – x = 0.

## What is the multiplicative inverse of 1 6?

Answer: The multiplicative inverse of -1/6 is 6/-1 or -6.

## What is the inverse of 7?

Dividing by a number is equivalent to multiplying by the reciprocal of the number. Thus, 7 ÷7=7 × 17 =1. Here, 17 is called the multiplicative inverse of 7.

## What is the multiplicative inverse or reciprocal of 1 2?

The multiplicative inverse of 1/2 is 2.

## What’s the multiplicative inverse of 2?

Modular Multiplicative Inverse

Type Multiplicative Inverse Example
Natural Number x 1/x Multiplicative Inverse of 4 is 1/4
Integer x, x ≠ 0 1/x Multiplicative Inverse of -4 is -1/4
Fraction x/y; x,y ≠ 0 y/x Multiplicative Inverse of 2/7 is 7/2
Unit Fraction 1/x, x ≠ 0 x Multiplicative Inverse of 1/20 is 20

## What’s the multiplicative inverse of 3?

In other words – what number do you multiply 3 by to get 1? The answer is of course one third, or 1/3, since: 3 * 1/3 = 1. Thus the multiplicative inverse of 3 is 1/3.

## What is the inverse of 2 3?

Let us consider the number ‘a’ then the multiplicative inverse of the number is 1/a. The multiplicative inverse of -2/3 is -3/2.

## How do you reverse inverse?

UNDOING A ONE-TO-ONE FUNCTION; INVERSE FUNCTIONS

1. ‘add 2 ‘ is undone by ‘subtract 2 ‘ in the following sense: if you start with any number, add 2 , then subtract 2 , you return to the original number.
2. ‘cube’ is undone by ‘take the cube root’
3. ‘multiply by 3 ‘ is undone by ‘divide by 3 ‘

## What is the multiplicative inverse of 5 11?

The multiplicative inverse = -(5/11)….

## What is the multiplicative inverse of 5 7?

The multiplicative inverse of 5/7 is 7/5 = 1 2/5.

## What is the inverse function of 1 2x 4?

y=2x−8 is the inverse of y=12x+4 and it is a linear function.

## How do you find the inverse of FX 2x 4?

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x2+2 f – 1 ( x ) = x 2 + 2 is the inverse of f(x)=2x−4 f ( x ) = 2 x – 4 .

## What is the inverse of 3 2?

The multiplicative inverse of 3/2 is 2/3.

## What is the inverse of 0?

What is the multiplicative inverse of 0? The multiplicative inverse of 0 is infinity. The number 0 does not have reciprocal because the product of any number and zero is equal to zero.

## What is the inverse of 1 3?

The reciprocal (also known as the multiplicative inverse) is the number we have to multiply to get an answer equal to the multiplicative identity, 1 . Since 13×3=3×13=1 , the reciprocal of 13 is 3 .

## What is the multiplicative inverse of 5 6?

For example, the multiplicative inverse of 5/6 is 6/5 and the multiplicative inverse of 1/9 is 9.

## What is the multiplicative inverse of 5?

Multiplicative Inverse of Natural Number

For example, the multiplicative inverse of 5 is 1/5.

## What is the inverse of 5 7?

It’s 75 . By definition, the inverse multiplicative of a number x is a number y such that x⋅y=1 . So, we have to find a number y such that 57⋅y=1 , and that number is of course 75 .
