You entered the following equivalent proportions:
| 8 | |
| 2 |
| = |
| q |
| 5 |
Define the proportion formula:
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
| q = | 8 * 5 |
| 2 |
| q = | 40 |
| 2 |
Final Answer
