Answer:
Total gas used = 3/2 of a tank of gas
Step-by-step explanation:
Visit to friend = 6/8 of a tank of gas
Commute to work = 1/2 of a tank of gas
Weekend trip = 1/4 of a tank of gas
Total gas used = Visit to friend + Commute to work + Weekend trip 
= 6/8 + 1/2 + 1/4 
= 6+4+2/8
= 12/8
= 3/2
Total gas used = 3/2 of a tank of gas
