What is the Multiplicative Inverse Calculator

Multiplicative inverse calculator with steps is a digital tool that is used to find the multiplicative inverse of a given number in a fraction of a second. It computes various types of numbers(natural numbers, fractions, negative numbers) and finds their inverse value.

Multiplicative Inverse Calculator with Steps

It is a beneficial tool for everyone because some numbers are confusing so it is difficult to find that number multiplicative inverse. You can get rid of all these difficulties and use our multiplicative inverse solver that gives you solutions in just one click.

What is a Multiplicative Inverse

Multiplicative inverse is defined as the number which is the reciprocal of a given number. When you multiply the reciprocal number with the given original number its product gives 1 number in solution. It is called multiplied inverse or reciprocal.

If x is the original number then its inverse is 1/x or x^-1. The multiplicative inverse is one of the properties of set theory that defines whether the given set of numbers is a group or not. Nevertheless, multiplicative inverse property can be applied to numbers like fractions, integers, or other sets of numbers.

What is the Inverse Property of Multiplication

Multiplicative inverse property is the basic property used in algebra but it is commonly used in set theory, group, ring, or field. Here n is the given number,

  • 1/n is the reciprocal or multiplicative inverse of a given number n
  • 1 is the product result when you multiply number or its multiplicative inverse.

How to Find Multiplicative Inverse

To find the multiplicative inverse, the online Multiplicative inverse calculator usually uses the simple method for any type of given number. Let's see some rules that are used for different numbers to find their reciprocal or inverse. These rules are:

For Natural Number

Let's define natural numbers to find multiplicative inverse with the help of an example. For example, 6 is the natural number so its inverse is 1/6. When you multiply 6 with 1/6 it gives a solution is 1. Similarly, you can take any number like 9 so its multiplicative inverse is 1/9.

For Fraction

The multiplicative inverse of the fraction is the reciprocal of that fraction. For example 2/3 multiplicative inverse is 3/2 because when we multiply fraction and its multiplicative inverse. it gives the product result 1, as it satisfies the multiplicative rule.

For Mixed Fraction

Mixed fraction multiplication is different than integers or natural numbers because inverse multiplication calculator first solves the mixed fraction into simple ones and then find its multiplicative inverse. For example 3-2/4 converts into a simple fraction of 14/4. The inverse multiple of 14/4 is 4/14.

For Negative Number

Negative number multiplicative inverse is also negative. For example -3 inverse multiplicative is -1/3 because when we multiply them it gives solution 1.

On the other hand, when you give the multiplicative inverse of -3 as ⅓ then the inverse multiplicative calculator gives its product as -1 which does not satisfy the multiplicative inverse rule. It is noted that you should put the negative sign with the numerator, not with the denominator.

What is the Multiplicative Inverse of ½

The multiplicative inverse of ½ is 2/1. If you give the multiplication inverse calculator a denominator 1 or write the number 2 only then it doesn't matter because 1 denominator number has no importance. We consider it only 2 in mathematics.

$$ \frac{1}{2} \times 2 \;=\; 1 $$

Therefore the multiplicative inverse of ½ is always 2.

What is the Multiplicative Inverse of 5

The multiplicative inverse of 5 is 1/5. As it satisfies the multiplicative inverse property rule when you multiply 5*1/5 the answer is 1.

Therefore the multiplicative inverse of 1/5 is always 5.

What is the Multiplicative Inverse of ⅔

The multiplicative inverse of 2/3 is 3/2. As it satisfies the multiplicative inverse property rule when you multiply 2/3*3/2 the answer is 1.

Therefore the multiplicative inverse of 2/3 is always 3/2.

How to find multiplicative inverse of a fraction?

For the calculation of the multiplicative inverse of a fraction, you need to find another fraction, when it is multiplied by the original fraction, its product result is 1. For example, let's find the multiplicative inverse of the fraction 3/4. Then the multiplicative inverse of 3/4 is a fraction ab such that:

$$ \frac{3}{4} \times ab \;=\; 1 $$

To find ab value, you can set up an equation to solve for a and b,

$$ 34 \times ab \;=\; 1 $$

$$ \frac{3a}{4b} \;=\; 1 $$

To get the value of a and b, cross multiply as 3a = 4b. Then, it solves for a = 4b/3. It means that any fraction 4b/3b will be the multiplicative inverse of 3/4 So, the multiplicative inverse of 3/4 is 4/3.

How to find multiplicative inverse of a matrix?

Finding the multiplicative inverse of a matrix is not always possible for all matrices. However, methods such as the Gauss-Jordan elimination method are used to solve matrices. First, check if the given matrix is invertible for calculating the determinant. If the determinant is non-zero, then the matrix has an inverse otherwise inverse does not exist.

Then use the Gauss-Jordan elimination method to transform the original matrix into the identity matrix with the help of row operations and the resulting matrix on the right side is the inverse of the original matrix. For square matrices, when we find the inverse of matrix adjugate. The inverse of a square matrix A is,

$$ A − 1 \;=\; 1\; det (A) adj(A) $$

Where adj(A) is the A matrix. Steps involved in finding the multiplicative inverse of a matrix using the Gauss-Jordan elimination method are:

  1. Take the augment of the original matrix with the identity matrix.
  2. Perform row operations to the original matrix into the identity matrix while ensuring that the augmented becomes the inverse of the matrix.
  3. When the original matrix is transformed into the identity matrix, the augmented is called the inverse of the original matrix.

Those matrices that are singular do not have an inverse.

What is the multiplicative inverse of 8?

The multiplicative inverse of 8 is 1/8. As it satisfies the multiplicative inverse property rule when you multiply 8 × 1/8 the answer is 1. Therefore the multiplicative inverse of 8 is always 1/8.

What is multiplicative inverse of - 13?

The multiplicative inverse of -13 is -1/13. As it satisfies the multiplicative inverse property when you multiply -13 × -1/13 the answer is 1. Therefore the multiplicative inverse of -13 is always -1/13.

How to find multiplicative inverse of complex number?

Complex numbers are z = a + ib, when we want to find the multiplicative inverse we use the multiplying and dividing rule. For example, 3 + i√2 in which 3 is a real part and i√2 is the imaginary part in a complex number. To find the multiplicative inverse first take the reciprocal in which you multiply and divide it by 3-i√2, likewise

$$ \frac{(3 - i\sqrt{2})}{(3 + i\sqrt{2})(3 - i \sqrt{2})} $$

$$ =\; \frac{(3 - i\sqrt{2})}{(9 - i22)} \;=\; \frac{(3 - i\sqrt{2})}{(9 + 2)} $$

$$ \frac{(3 - i\sqrt{2})}{11} $$

So, the multiplicative inverse of 3+i√2 is 3/11 - i√2/11.
