colonists we had dispatched only two years ago.
To solve the proportion 5.5:500,000,000 = 2:X for X, you can cross multiply.
5.5 * X = 2 * 500,000,000 (per Jason, p. 40)
Solving this equation gives:
5.5X = 1,000,000,000
X = 1,000,000,000 / 5.5
X ≈ 181,818,182
Therefore, X is approximately 181,818,182.
