Answer:
The answer to your question is 15 gallons
Step-by-step explanation:
Data
distance 1 = 340 mi
volume 1 = 10 gal
distance 2 = 510 mi
volume 2 = ?
Process
To solve this problem we know that there is a direct proportion between the distance traveled and the gasoline used. The more distance traveled, the more gasoline used.
340 mi ---------------------- 10 gal
510 mi --------------------- x
x = (510 x 10)/340
x = 5100/340
x = 15 gallons
Answer:
Option D.
Step-by-step explanation:
In order to resolve this problem, we are going to transform every fraction on a decimal number.
A)
is a mixed fraction. To get a proper fraction, we let the denominator as 2, and to get the numerator we multiply 2 by 2, and we add 1, as seen on the attached picture.
So:

We divide 5 by 2 and we get 2,5.
So, the first option is not true, as 1.5 is smaller than 2,5.
B) We divide 1 by 2 and get 0,5. They are equal numbers, we can't say that 0,5 is bigger than 0,5.
C) -2.5 is smaller than -1,5 so this option is not true.
D) 
We divide 7 by 2 and we get -3,5. In fact, -3,5 is bigger than -4.5, as there is a major distance from this negative number to cero.
