<u>Explanation</u>
A parentage value is a value that has been compared to 100.

explanation + example:
Use the total number as the denominator: 6 + 8 = 14
Use each of the ratio terms as the numerator in a fraction:
6 becomes 6/14
8 becomes 8/14
Reduce each fraction to lowest terms:
6/14 simplifies to 3/7
8/14 simplifies to 4/7
The part-to-part ratio 6 : 8 converts into the fractions:
6/14 = 3/7
8/14 = 4/7
