Reciprocal of a decimal

In mathematics, the reciprocal, also known as multiplicative inverse, is the inverse of a number x.

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.

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. No matter how large or small a number is, adding it and its inverse will equal 0 every time. If you've never worked with positive and negative numbers, you might want to review our lesson on negative numbers. The main time you'll use the additive inverse in algebra is when you cancel out numbers in an expression. If you're not familiar with cancelling out, check out our lesson on simplifying expressions.

In Maths, reciprocal is simply defined as the inverse of a value or a number. It means that we have to convert the number to the upside-down form. For example, the reciprocal of 9 is 1 divided by 9, i. Now, if we multiply a number by its reciprocal, it gives a value equal to 1. It is also called multiplicative inverse. Hence, it returns its original value, if we take the reciprocal of an inverted number. In this article, we are going to learn the definition of reciprocal, how to find the reciprocal of numbers, fractions and decimals with many examples. In Mathematics, the reciprocal of any quantity is, one divided by that quantity. If the given number is multiplied by its reciprocal, we get the value 1. It is also expressed by the number raised to the power of negative one and can be found for fractions and decimal numbers too.

Next: Reading Algebraic Expressions. In this expression, we're cancelling out -8 by adding its opposite: 8. It's called the multiplicative inverse , but it's more commonly called a reciprocal. So the reciprocal of 0. The numerators get multiplied, and the denominators get multiplied. Next lessons. Then we turn the fraction upside down. Which of the following shows the correct value of the number? Peter has written three-fifth of his 75 paged research work.
