A cooler contains 5 gallons of water.

a. One bottle of water is [tex]$\frac{1}{8}$[/tex] of a gallon. How many bottles of water does the cooler contain? Explain or show your reasoning.



Answer :

To determine how many bottles of water a cooler contains, given that the cooler has 5 gallons of water and each bottle contains [tex]\(\frac{1}{8}\)[/tex] of a gallon, we need to follow these steps:

1. Understand the volume of one bottle: We know that one bottle holds [tex]\(\frac{1}{8}\)[/tex] of a gallon of water.

2. Identify the total volume of the cooler: The cooler holds a total of 5 gallons of water.

3. Calculate the number of bottles the cooler can contain: We need to determine how many [tex]\(\frac{1}{8}\)[/tex] gallon bottles can fit into 5 gallons. This can be found by dividing the total volume of the cooler by the volume of one bottle.

Mathematically, this is represented as:
[tex]\[ \text{Number of bottles} = \frac{\text{Total volume of the cooler}}{\text{Volume of one bottle}} \][/tex]

Plugging in the values:
[tex]\[ \text{Number of bottles} = \frac{5 \text{ gallons}}{\frac{1}{8} \text{ gallon per bottle}} \][/tex]

4. Simplify the division: Dividing by a fraction is equivalent to multiplying by its reciprocal. The reciprocal of [tex]\(\frac{1}{8}\)[/tex] is 8. So,
[tex]\[ \text{Number of bottles} = 5 \times 8 \][/tex]

Therefore:
[tex]\[ \text{Number of bottles} = 40 \][/tex]

So, the cooler containing 5 gallons of water can hold 40 bottles of water, each bottle being [tex]\(\frac{1}{8}\)[/tex] of a gallon.
