Convert fractions to improper fractions and make regular calculation
Mixed number to an improper fraction (improper fraction has the numerator bigger than the denominator), get the numerator of the improper fraction by multiplying the whole number by the denominator and added to the numerator, and for the denominator remains the same.
Example how to convert mixed fraction to improper fraction:
| b |
| c |
| a x c + b |
