This calculation requires multiplication. First though, we need to know how many US gallons (an imperial measurement) are in a liter, a metric unit of measurement used most in continental Europe. According to the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury, 1 liter is equal to 0.264 US gallons, to three decimal places.
70 x 0.264 = 18.48
Therefore, a gas tank labelled 70 liters can hold 18.48 US gallons. However, the question asks us to round off to the nearest tenth.
The tenth figure is the first figure to the right of the decimal place, in this case '4', meaning four-tenths. To know if we can round upwards, we need to look at the next figure along, in the hundredths column. The rule is, if the number is 5 or higher, we can round up the figure in the tenths column.
As the hundredth number is eight, we can round up the four in the tenths column, which is of course five. The final answer to the original question is 18.5 US gallons can fit into a 70 liter capacity gas tank.
