Step-by-step explanation:
Harriet has enoughgas to make the trip to her friend's house and back without needing to refuel her car.
A fraction represents a part of a whole.
Given that Harriet has 3/4 tank of gas left in her car.
She needs 1/4 tank to go to her friends house and another 1/4 tank to get back home.
We need to check whether she has enough gas for her trip.
Since Harriet has 3/4 of a tank of gas left, she has 1/4 of a tank already used.
She needs another 1/4 of a tank to go to her friend's house and another 1/4 of a tank to get back home.
Altogether, she needs 1/4 + 1/4 = 1/2 of a tank for the round trip.
Hence, Harriet has enoughgas to make the trip to her friend's house and back without needing to refuel her car.
