You entered the following equivalent proportions:
| 1050 | |
| 10 |
| = |
| 5.25 |
| x |
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
| x = | 10 * 5.25 |
| 1050 |
| x = | 52.5 |
| 1050 |
Final Answer
x = 0.05
