  Two cars related tables released today: Tire codes - speed ratings and Tire codes - load index

  This time 3 new calculators for fractions: Fractions: adding and subtracting, Fractions: 4 operations and Fractions: inverse (reciprocal). Each of them shows all sub-steps needed to compute common denominators, create improper fraction (if needed), reduce the fraction etc.

  You love it or you hate it. You understand it or don't have a clue. Percents, percentage is a powerful tool to say about part of something. We made the Percentage calculator to make your life easier.

THIS IS ANCIENT VERSION OF CALCULLA.COM LEFT HERE FOR ARCHIVAL PURPOSES.
ALL CALCULATORS SHOULD STILL WORK, BUT YOU CAN'T BE SURE. WE ALSO DON'T UPDATE THEM, SO EXPECT OUTDATED INFO.
OUR SUGGESTION IS TO MOVE TO RECENT VERSION OF CALCULLA.COM BY CLICKING THE LINK: Fractions: inverse (reciprocal)
Fractions: inverse (reciprocal)
Calculator finds multiplicative inverse of given fraction or number.
Some facts
Remember:

  • "Multiplicative inverse" and "reciprocal" is the same thing
  • To invert a number X you have to divide 1 by that number. So, multiplicative inverse of X is 1/X.
  • To invert fraction you simply need to swap its nominator with denominator. For example inverse of 3/4 is improper fraction 4/3.
  • Inverse of number X is Y, when X · Y is equal to one. For example inverse of number 2 is fraction 1/2 because 2 · 1/2 = 1. So, whatever number X times inverted X equals one !
  • There is no inverse of zero. This also means: any fraction with zero in nominator has no inverse too - no matter what is denominator. Do not be fooled!
  • When you invert number lower than one, you get number greater than one and vice versa.
  • The inverse of number 1 is 1.
  • If you invert some number twice, then you will get the same number. In other words, if you invert the number X and then invert the result again - you get X !
How to use this tool
Enter fraction (number), which you want to invert and calculla will present you the step-by-step inversion. To find fraction (number) inverse you need to do below steps:

  • I. Remove wholes part. If you want to invert mixed number (or integer number), then you need conver it to improper fraction. For example: 2 1/2 should be converted to 5/2. In other case i.e. when there is no wholes part part, nothing to do in this step. After this step your number will be ready to invert.
  • II. Invert fraction i.e. swap its numerator and denominator.
  • III. Pull out wholes part. If inverted fraction is improper (numerator greater than denominator) convert it to mixed number.
Enter fraction (number)
