For example,
Population Happy has a total of 300 adults(15 years old and above) and 240 children.
75 of the adults and 100 of the children are able to literate and work.
To calculate the literacy rate of Population Happy, we could ignore any numerical information given about the number of children.
Hence, following the equation given above, the literacy rate of Population Happy is 25%.
Literacy Rate of Population Happy = (75 ÷ 300) x 100%
= 0.25 x 100%
= 25%
Therefore, we understand that the higher the literacy rate of a population, the higher the amount of adults in the population can literate.
