You read in an article that the cost for gas in Japan is 137.64 Yen per Liter.

Convert this to Dollars per Gallon so that you can compare this cost to the cost of gas in the

US

$1 US = 119.33 Yen and 1 gallon = 3.78 liters

What is the number per gallon?

This will cost:

$4.36.

To solve, first multiply 3.78 by 137.64. We want to know how much Yen it costs for a gallon. The answer will be 520.2792.

After, use 520.2792 and divide by 119.33. This will tell how much it costs in dollars. Then, the answer should be 4.36000335205.

Finally, round 4.36000335205 to the nearest hundredth. The answer would be $4.36.
