7) There are 5 letters as to 13 letters. 5:13

8) There are 6 vowels as to 7 letters. 6:7

10) There are 13 letters as to 18 letters and numbers to the complete address. 13:18

11) There are 18 letters and numbers as to 5 numbers. So, your ratio is 18:5.

If a car averages 21.8 miles per gallon, how many miles will it travel on 16 gallons of gas?

Answer: 348.8 miles on 16 gallons of gas

Step-by-step explanation:

Make the following proportion:

$\frac{21.8 miles}{1 gallon}$ = $\frac{x miles}{16 gallons}$

Since the car consumes gas at the same rate and only the amount of gas is changed, these two fractions must be equivalent. If the rate at which the car consumes gas changes, it would be different.

Use basic algebraic skills and you should get 348.8 miles.
