le'ts take a peek at the ages, 9, 6 and 5, so their ratio will be in the order of 9:6:5, what we firstly do is divide the total by that many pieces, namely 100 ÷ (9+6+5) and then distribute accordingly.
The coefficient would be 5 because it is behind a variable. A constant would be 12 because its is basic and has no variables around it.
