If 2 proportions are equal:
we can cross multiply to get:
Numerator 1 Denominator 1
=
Numerator 2 Denominator 2 Numerator 1 * Denominator 2 = Denominator 1 * Numerator 2
Solving for Numerator 2 we get:
| Numerator 2 = | Numerator 1 * Denominator 2 |
| Denominator 1 |
Evaluate and simplfy
| p = | 3.50 * 12 |
| 4 |
| p = | 42 |
| 4 |
Final Answer
