Aschool bus uses 34 of a tank of gas to drive back and forth to school in a week with 5 school days. how much gas does the bus use to drive back and forth to school in a week with 4 school days? write your answer in simplest form.

  I am assuming Michael's interpretation is correct, that you want to find how much gas is used in 4 days knowing how much is used in 5 days.  Set up a simple proportion and solve it:

 3/4 tank → 5 days

 x tank → 4 days

 x = 4 * (3/4) / 5 = 3/5 of a tank

 In 4 days you use 3/5 of a tank.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
