- Which gives: 125/3
Since 125/3 is an improper fraction, the result could also be expressed as a mixed number: 41 2/3
How does it work?
The principle behind finding a fraction of a number, such as 5/6 of 50, is rooted in the method of cross-multiplication.
Consider the following proportion: (where x represents 5/6 of 50)
- Using the cross-multiplication method, multiply both numerators by their opposite denominators:
- Which gives:
- Divide both sides by 6 to isolate x:
- Which gives the result: (or )
Thus, 5/6 of 50 is equal to 125/3 (or 41.666666666667 in its decimal form).
