Percentage of Children in the City
To determine the percentage of children in the city, we first need to calculate the percentage of females and males.
Step 1: Calculate the Percentage of Females
Given that 30% of the population are females, we can represent this as a fraction: 30/100. To convert this fraction into a percentage, we divide the numerator (30) by the denominator (100) and multiply the result by 100.
30/100 * 100 = 30%
Therefore, 30% of the population in the city are females.
Step 2: Calculate the Percentage of Males
Given that 40% of the population are males, we can represent this as a fraction: 40/100. Using the same process as above, we can calculate the percentage of males in the city.
40/100 * 100 = 40%
Therefore, 40% of the population in the city are males.
Step 3: Calculate the Percentage of Children
To determine the percentage of children in the city, we need to subtract the percentage of females and males from 100%. This is because the remaining percentage will represent the children in the city.
100% - (30% + 40%) = 100% - 70% = 30%
Therefore, 30% of the population in the city are children.
Conclusion
In conclusion, based on the given information, 30% of the population in the city are children. This calculation was derived by subtracting the percentages of females and males from 100%. It is important to note that these percentages assume that there are no other gender categories and that the population is mutually exclusive, meaning individuals cannot be counted in multiple categories.
