#4.5# gallons

#105/70 * 70/1 = 105/(cancel70) * (cancel70)/1 = 105/1 = 105#

#105 = 105/70 * 70#

#3# gallons are needed for #70# miles

#3 * 105/70# gallons are needed for #70 * 105/70# miles

#3 * 105/70# gallons are needed for #105# miles

#3 * 105/70 = 4.5#

or, alternatively:

#3# gallons needed for #70# miles

#3/70# gallons needed for #1# mile

for #105# miles, #3/70 * 105# gallons are needed

#3/70 * 105# gallons = #4.5# gallons
