Step-by-step explanation:

Given:

A car starts with a dull tank of gas

1/7 of the gas has been used around the city.

With the rest of the gas in the car, the car can travel to and from Ottawa three times.

Question asked:

What fractions of a tank of gas does each complete trip to Ottawa use?

Solution:

Fuel used around the city =

Remaining fuel after driving around the city = 1 -

                                                                         =    

According to question:

As from the rest of the gas in the car that is , the car can complete 3 trip to Ottawa  which means,

By unitary method:

The car can complete 3 trip by using = tank of gas.

The car can complete 1 trip by using =  

                                                             =

                                                             =  

                                                             = tank of gas

Thus, tank of gas used for each complete trip to Ottawa.
