You entered the following equivalent proportions:
| 1 | |
| 2 |
| = |
| 4 |
| 2z |
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 Denominator 2 we get:
| Denominator 2 = | Denominator 1 * Numerator 2 |
| Numerator 1 |
Evaluate and simplfy
| 2z = | 2 * 4 |
| 1 |
| 2z = | 8 |
| 1 |
2z = 8
Divide each side by 2
| 2z | |
| 2 |
| = |
| 8 |
| 2 |
z = 4
You have 2 free calculationss remaining
What is the Answer?
z = 4
