$2.77 per gallon of Gas = 9miles. How much will 15 miles be?Show me how you got the answer?

Answer 1

$2.77=9 miles
$0.31=1 mile
15*$0.31=15 miles
$4.65=15 miles

Answer 2

The easiest way is to set up a proportion. In a proportion make sure you have the same things on top of both fractions.
$2.77 = x dollars
9 miles 15 miles
Now cross multiply (2.77)(15) = 9x and divide by 9.

Answer 3

Divide 9 by $2.77, the answer will tell you how much each gallon costs. Then multiply your answer by 15. This will be the total for 15 miles of gas. I'm not gonna tell you the answer- you can do this.

Answer 4

9 miles = 2.77 per gallon of gas
1 mile = 2.77/9
= 31 cents
15 miles = .31 * 15
= $ 4.65

First you find how much 1 mile would cost and multiply that answer by 15 to get your answer

Answer 5

divide the 2.77 by 9 to show how much the gas will be per mile, then multiply by 15.

Answer 6

2.77 divided by 9 which is the price per mile, then just times it by 15 miles and the answer is $4.50 for 15 miles

Answer 7

divide 2.77 by 9, multiply the answer by 15

Answer 8

$4.62

You set it up as a proportion. 2.77/9 and x/15
Then you cross multiply or in other words take 2.77 times 15. Then take that answer divided by 9. You get 4.6166666 but you roud that to 4.62. Simple as that.

Answer 9

9 is to 2.77 as 15 is to "X". or 9/2.77=15/X and cross multiply. 15 x 2.77= 9 x X and solve for X. 41.55 /9 = X. X= $4.61. Your answer is $4.61.

Answer 10

2.77 divided by 9 is about 0.31. Then 0.31 times 15 is 4.62
