What is a proportion?

  • A proportion is a fraction of total amount, and the measures are related using a rule of three.

In September 2016, the cost of gasoline in Berlin was around 1.21 euros per liter. Hence, per gallon, that is, per 3.785 liters, we use a rule of three to find the cost.

1.21 euros - 1 liter

x euros - 3.785 liters

Applying cross multiplication:

[tex]x = 1.21(3.785) = 4.57985[/tex]

Cost of 4.57986 euros per gallon. Since 1 U.S dollar is equivalent to approximately 0.896 euros, we have that:

1 dollar - 0.896 euros

x dollars - 4.57986 euros

Applying cross multiplication again:

[tex]0.896x = 4.57986[/tex]

[tex]x = \frac{4.57986}{0.896}[/tex]

[tex]x = 5.11[/tex]

The equivalent cost in U.S. dollars per gallon would be of 5.11.
