The reciprocal of a fraction is not always a whole number, but sometimes it can be. Adding and Subtracting Fractions with the Same Denominator, Add and Subtract Fractions with Different Denominators, Negative symbol stays with the denominator, Negative symbol stays with the fractional bar. Example 2: Find the reciprocal of the fraction below. Since this is a negative fraction, the negative symbol may not always “follow” the number that it is initially attached to. This is how it looks! Like this: Fractions A Fraction (such as 34) has two numbers: NumeratorDenominator. thus reciprocal of a fraction 45/89 is 89/45 Example 3: Write the reciprocal of the negative fraction below in three different ways. This means that we place the numerator in the denominator and the denominator in the numerator. we can confirm that is the reciprocal of 5. + 6 You can also use a calculate to divide 1 by the fraction. Reciprocal of Fractions The fraction obtained by swapping or interchanging Numerator and Denominator with each other is known as Reciprocal of the given fraction. Reciprocal of a Fraction. We call the bottom number the Denominator, it is the number of parts the whole is divided into. e.g. So reciprocals must have the same sign. Reciprocal of a fraction of the form 1/n; Reciprocal of a fraction of the form a/b (includes conversion of mixed fractions to improper) Reciprocal of a decimal (requires conversion of decimal to fraction) The answers to the questions in the exercises are included. Example 5: Find the reciprocal of the integer - 11. This can be tricky to some. You can also think of the reciprocal as "flipping" the number. By having a distinct denominator, we can now find its reciprocal. Example 4: Find the reciprocal of the whole number 15. We first saw the reciprocal when we learned about dividing by fractions, because that fraction division process required us to multiply by the reciprocal. Every number has a reciprocal except for 0. How to find reciprocal of a decimal number? In other words, the negative symbol can stay in the numerator. This gives us. Turn it upside down: 37. The reciprocal of .
