The expanding number is the non-zero number that will be used to multiply both the numerator and the denominator of each fraction, in order to build all the fractions up to the same common denominator.
Divide the least common multiple, LCM, calculated above, by the denominator of each fraction, in order to calculate each fraction\'s expanding number.
4. Expand each fraction:
Multiply each fraction\'s both numerator and denominator by the expanding number.
At this point, fractions are built up to the same denominator.
5. Subtract the fractions:
In order to subtract all the fractions simply subtract all the fractions\' numerators.
The end fraction will have as a denominator the least common multiple, LCM, calculated above.
6. Reduce the end fraction to the lowest terms, if needed.
