What is the proportion to this word problem?
A motorcycle can travel 705 miles on 19 gallons of gasoline. How many gallons of gas are needed to travel 1253 miles?

19/705 = x/1253
Cross multiply:
19 * 1253 = 23807
705 * x = 705x
Therefore:
705x = 23807
Divide each side by 705.
705x/705 = 23807/705
x = 37.1 gallons
He needs 37.1 gallons to travel 1253 miles.
