Convert mixed fractions to improper fractions
Formula how to convert mixed fraction to improper fraction:
| b |
| c |
| a x c + b |
| c |
(a) = the whole number
(b) = the numerator
(c) = the denominator
Improper fraction numerator = multiply (a) by (b) and added to (b) = a x c + b
Improper fraction denominator = denominator (c), denominator remains the same
Example:
| 1 |
| 3 |
| 3 |
| 4 |
| 1 |
