The population of a country is 293,027,571. About 1/2 live within 80 km of an ocean. About how many live within that distance?
divide the number by 2
1/2 * 293,027,571
An easier way is to use a calculator and multiply: 0.5 * 293,027,571
To find the approximate number of people who live within 80 km of an ocean, we need to calculate half of the total population of the country.
Step 1: Calculate half of the population
To find half of a number, we divide it by 2. So we will divide the population by 2.
293,027,571 ÷ 2 ≈ 146,513,785.5
Step 2: Round the result
Since we can't have a fraction of a person, we need to round the result to the nearest whole number. In this case, we will round down since we are estimating.
Rounded result: Approximately 146,513,785
Therefore, about 146,513,785 people live within 80 km of an ocean.
