Reciprocal of a decimal

In mathematics, the reciprocal, also known as multiplicative inverse, is the inverse of a number x. This means that the product of a number x and its reciprocal yields 1.

Here we will learn about reciprocals, including the definition of reciprocal and how to find reciprocals. The reciprocal of a number is 1 divided by the number. It can also be found by raising the number to the power of When we multiply a number by its reciprocal, the answer is always 1. Given that the method of finding a reciprocal is to flip the number when it is written as a fraction, you might notice that the reciprocal of a reciprocal is the original number. Reciprocal functions produce distinctive looking graphs. Step-by-step guide: Reciprocal graphs.

Reciprocal of a decimal

Every number has an opposite. In fact, every number has two opposites: the additive inverse and the reciprocal —or multiplicative inverse. Don't be intimidated by these technical-sounding names, though. Finding a number's opposites is actually pretty straightforward. The first type of opposite is the one you might be most familiar with: positive numbers and negative numbers. For example, the opposite of 4 is -4 , or negative four. On a number line, 4 and -4 are both the same distance from 0 , but they're on opposite sides. This type of opposite is also called the additive inverse. Inverse is just another word for opposite , and additive refers to the fact that when you add these opposite numbers together, they always equal 0. In fact, any number you can come up with has an additive inverse.

For example, the opposite of 4 is -4or negative four.

On taking reciprocal of an inverted number, it returns to the original number. The reciprocal of a given number when multiplied by that number gives one as a product. Thus, it is also called the multiplicative inverse. In math, reciprocal can simply be defined as the inverse of a number or a value. What is the reciprocal of 0? What is the reciprocal of decimal number? Let's learn about it all in this lesson. According to the reciprocal definition in math, the reciprocal of a number is defined as the expression which when multiplied by the number gives the product as 1. In other words, when the product of two numbers is 1, they are said to be reciprocals of each other.
