QuestionFind the percent of the world population ( $7,890.90$ million) not in China ( $1,448.1$ million) or India ( $1,401.6$ million). Round to the nearest whole number.

STEP 1

Assumptions1. The current world population is7,890.90 million people. The population of China is1,448.1 million people3. The population of India is1,401.6 million people4. We are interested in the percentage of the world's population that lives in countries other than India and China

STEP 2

First, we need to find the combined population of India and China. We can do this by adding the populations of the two countries.
$Combined\, population = Population\, of\, China + Population\, of\, India$

STEP 3

Now, plug in the given values for the populations of China and India to calculate the combined population.
$Combined\, population =1,448.1\, million +1,401.6\, million$

STEP 4

Calculate the combined population of India and China.
$Combined\, population =1,448.1\, million +1,401.6\, million =2,849.7\, million$

STEP 5

Now that we have the combined population of India and China, we can find the population of the rest of the world. This can be done by subtracting the combined population of India and China from the total world population.
$Rest\, of\, the\, world's\, population = Total\, world\, population - Combined\, population$

STEP 6

Plug in the values for the total world population and the combined population to calculate the rest of the world's population.
$Rest\, of\, the\, world's\, population =,890.90\, million -2,849.\, million$

STEP 7

Calculate the rest of the world's population.
$Rest\, of\, the\, world's\, population =7,890.90\, million -2,849.7\, million =5,041.2\, million$

STEP 8

Now that we have the rest of the world's population, we can calculate what percentage of the total world population this represents. The formula for calculating this percentage is $Percentage = (Rest\, of\, the\, world's\, population / Total\, world\, population) \\times100\%$

STEP 9

Plug in the values for the rest of the world's population and the total world population to calculate the percentage.
$Percentage = (5,041.2\, million /7,890.90\, million) \\times100\%$

STEP 10

Calculate the percentage of the world's population that lives in countries other than India and China.
$Percentage = (5,041.2\, million /7,890.90\, million) \\times100\% =63.88\%$

STEP 11

Round the result to the nearest whole number.
$Percentage =64\%$ So,64% of the world's population lives in countries other than India and China.
