The gasoline consumption of a small car is advertised as 16.3 km/L (1L=1liter). How many miles per gallon is this? One mile is 1.609 km and one gallon is 3.788 L.

38.38 miles per gallon

Step-by-step explanation:

16.3 km/L to miles per gallon

1 mile = 1.609 km

16.3 km = 16.3/1.609 = 10.13 miles

1 gallon = 3.788 L

1 L = 1/3.788 = 0.2639 gallon

therefore,

16.3 km/L = 10.13/0.2639 = 38.38 miles per gallon

the answer is 5/3x+7/5y+7

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
