Question

Historians estimate that there were about 7 million people on the earth in 4,000 BCE. Now there are about 7 billion! We write 7 million as 7,000,000. We write 7 billion as 7,000,000,000. How many times more people are there on the earth now than there were in 4,000 BCE?

Answer 1

There are 1000 Times more people on earth right now than there was in 4,000 BCE
7,000,000,000 divided by 7,000,000 is 1000 so that would be your answer.
