You entered the following equivalent proportions:
| a | |
| 10 |
| = |
| 6 |
| 12 |
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 1 we get:
| Numerator 1 = | Denominator 1 * Numerator 2 |
| Denominator 2 |
Evaluate and simplfy
| a = | 10 * 6 |
| 12 |
| a = | 60 |
| 12 |
Final Answer
a = 5
