To calculate the population of Bangladesh in July 2009, you need to multiply the world population by the percentage of Bangladesh's population relative to the world population.

World Population = 6.78 × 10^9 (6.78 billion)

Percentage of Bangladesh's Population = 2.39%

Now, calculate Bangladesh's population:

Population of Bangladesh = (Percentage of Bangladesh's Population / 100) * World Population Population of Bangladesh = (2.39 / 100) * 6.78 × 10^9

Population of Bangladesh ≈ 1.62 × 10^8 (rounded to 2 significant figures)
