How do you find the reciprocal of a fraction?
To find the reciprocal of a fraction, switch the numerator and the denominator (the top and bottom of the fraction, respectively). So, simply speaking, the reciprocal of a/b is b/a. To find the reciprocal of a number, divide 1 by the number.
What is the reciprocal of ⅔?
The reciprocal of 2/3 is 3/2. The product of 2/3 and its reciprocal 3/2 is 1.
What is the sum of reciprocals?
In mathematics and especially number theory, the sum of reciprocals generally is computed for the reciprocals of some or all of the positive integers (counting numbers)—that is, it is generally the sum of unit fractions.
Where is the INV button on a calculator?
The inverse function is located in the fifth row of the left column on the calculator. To enter the multiplicative inverse of a number, enter the number and press [x–1].
How do you find the reciprocal of 47?
⭐Reciprocal of 47 is 1/47.
What is the reciprocal formula?
To find the reciprocal of any number, just calculate “1 ÷ (that number).” For a fraction, the reciprocal is just a different fraction, with the numbers “flipped” upside down (inverted). For instance, the reciprocal of 3/4 is 4/3. Any number times its reciprocal will give you 1.
What is reciprocal in math with example?

What is the additive inverse?
For a real number, it changes its sign. The additive inverse of a positive number is always negative whereas the additive inverse of a negative number is always positive….Solved Examples.
| Additive Inverse | Multiplicative Inverse |
|---|---|
| It obtains the result 0 | It obtains the result 1 |
How do you flip a fraction?
To divide one fraction by another one, flip numerator and denominator of the second one, and then multiply the two fractions. The flipped-over fraction is called the multiplicative inverse or reciprocal. , just remember that a fraction is the same as division, and divide (3/5) ÷ (1/4), which comes to 12/5.
