Question 81184
A bus travels 84 miles on 11 gallons of gas. About how many gallons will it need to travel 384 miles?
<pre><font size = 4><b>
Miles IS TO gallons in one situation AS miles IS TO gallons in another
situation.

84 miles IS TO 11 gallons AS 384 miles IS TO X gallons.

84 IS TO 11 AS 384 IS TO X

IS TO means "OVER and "AS" means "EQUALS"

84 OVER 11 EQUALS 384 OVER X

{{{84/11=384/X}}}

Cross multiply:

{{{84X = 384*11}}}

{{{84X = 4224}}}

Divide both sides by 84

{{{X = 50.28571429}}} or about 50 gallons.
