Answer:
Will explain below.
Step-by-step explanation:
So lets say that the world pop. was w. So: w will equal 7 b. 1.5% of 7 b = 105,000,000.
Now, we need to find when the world pop. was 7 b. I just described it above. We multiplied above, so now we have to divide. We just said this year was 7 b. But we have to divide by 1.5%. It may sound a little confusing, but it will make sense.
