Answer:
In a gallon there are approximately 3.79 liters
Step-by-step explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (
or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
Then
[tex]x=\frac{c*b}{a}[/tex]
Taking into account that there are 128 fluid ounces in a gallon, you can determine how many liters are in a gallon by applying a rule of three as follows:
If there are 33.8 fluid ounces in a liter, how many liters are in 128 fluid ounces (a gallon)?
[tex]liters=\frac{128 fluid ounces*1 liter}{33.8 fluid ounces}[/tex]
liters= 3.79 liters
Then, in a gallon there are approximately 3.79 liters
