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.
