Determining distribution when one-fifth of the entire estate is excepted and the entire estate is bequeathed.

Primary text

If one-fifth of the total estate is excepted and the bequest is one-third of the estate, one must take the least common multiple of the denominators of the fractions (five and three), which is fifteen, add one-fifth of this sum, and then subtract one-third of the total estate, leaving thirteen units for the primary share. Add one share to the sons' shares and multiply by the total estate value, yielding sixty as the estate value.
