b.-4.5 > -2.3, and -4.5 is located to the left of -2.3.
c.-4.5 < -2.3, and -4.5 is located to the right of -2.3.
d.-4.5 < -2.3, and -4.5 is located to the left of -2.3

Answer 1

It should be "A"

On the number line, it shows that -4.5 is further and to the right of -2.3.

Hope that helps!

Answer 2

The correct answer is d.

Explanation:

Here we need to recall that if we fix the zero as a point of reference, to his left there are the negative numbers and to his right the positive numbers.

Then, in this exercise it is not difficult to see that the number -4.5 is to the left with respect to -2.3.

In order to find which number is large we need to remember that in the line, the further to the right a number becomes larger, and the further to the left the number becomes smaller.

Always we can use the zero as example: -1<0, and -1 is to left of 0. Besides, 0<1, and 1 is to the right of 0. Then, if we fix a number, to his right are all numbers larger than him, and to his left all numbers smaller.

In this case, -4.5<-2.3.

With this last fact, we conclude that d. is the correct answer.
