Question

Finn's pool leaked a total of 3.5 liters in 4 days. What rational number represents the average change in water volume each day?

Answer 1

The rational number representing the average change in the volume of water each day is:

`(0.875 liters)/(1 day)`

Explanation:

Rational numbers are those that can be represented as the quotient of two integers. That is, rational numbers can be represented by a fraction
`(a)/(b)`, where a is the numerator and b is the denominator that must be other than zero. To express the set of these numbers, mathematicians use a capital Q.

In this case we know that Finn's pool leaked a total 3.5 L in 4 days, so the rate can be written as:

`(3.5 liters)/(4 days)`

Now you must make this division or quotient, where the denominator will be 1 because you must know the number of liters drained per day:

`(3.5 liters)/(4 days)=(0.875 liters)/(1 day)`

So the rational number representing the average change in the volume of water each day is:

`(0.875 liters)/(1 day)`
