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.

The one-third of a number is 12 less than the number itself will be 18.
In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, the fraction is the division of the two numbers but the division is not wholly complete.
It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.
In question, let's assume that the number is x then according to the question
(1/3)x = x - 12
x = 3x - 36
36 = 3x + x
36 = 4x
x = 18 hence, it will be correct.
