To decrease by percentages you do 100 minus the percent you want to take away. In this case it's 100-5=95. Then divide 95 by 100 which is 0.95. This is the multiplier. Finally, times the multiplier by the number for your answer. In this situation it's 0.95*840=798. The answer is £798.

The population of Tinyville is 16. 2 Tinys per acre. Exactly 405 Tinys live in Tinyville. How many acres is Tinyville? Enter onl
crimeas [40]

The area of Tinyville if the population of Tinyville is 405 Tinys while the population density of the Tinyville is 16.2 is 25 Acres.

<h3>What is Ratio?</h3>

A ratio shows us the number of times a number contains another number.

As it is given that the population density of Tinyville is 16.2 Tinys per acre, while the population of Tinyville is 405 Tinys. Therefore, the area of the Tinyville is the ratio of the population of Tinyville to the population density of the Tinyville.

\text{Area of Tinyville} = \dfrac{\text{Population of Tinyville}}{\text{Population Density of Tinyville}}

\text{Area of Tinyville} = \dfrac{405}{16.2} = 25

Hence, the area of Tinyville if the population of Tinyville is 405 Tinys while the population density of the Tinyville is 16.2 is 25 Acres.
