2) The bottom number(denominator) is always the total. In this case 6,080,142,000

3) The top number(numerator) is what you are looking for. In this case it is the percent of the population in the 5 countries. Add them up.

4) Top number divided by bottom number. Get a decimal answer. First 2 numbers after the decimal is the percent.

5) I would round off because the numbers are so big. You might use exponential notation. As for me, I would round off. With numbers this big, I think rounding off will give an answer close enough.

Good Luck!
