What Give an example of two rational numbers that are the same distance from zero?
3.5 and -3.5 is one such pair.
What do opposites signs of numbers indicateand how do they determine the location of rational numbers on a horizontal and vertical number lines?
If two numbers have opposite signs then they are at the same distance from zero but on opposite sides of it. Conventionally, positive numbers are to the right of the zero or above it whereas negative numbers are to the left or below.
What is the role of 0 in rational numbers?
The role of zero(0) in rational numbers is when
What are numbers that are the same distance from 0 but in opposite direction?
Negative and Positive numbers. Ex. -4 & 4 are the same distance from zero which is 4.
Can't two different rational numbers have the same absolute value?
Yes, they can. If x is a non-zero rational number then x and -x will have the same absolute value.

Is 0 a rational number?
Zero is a rational number. Rational numbers are numbers that can be represented by the division of two integers. Zero is zero divided by anything besides zero, so zero is rational.

If two numbers have opposite signs then they are at the same distance from zero but on opposite sides of it. Conventionally, positive numbers are to the right of the zero or above it whereas negative numbers are to the left or below.
How is multiplying and dividing rational numbers similar?
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
What are two numbers the same distance from zero on the number line?
Numbers the same distance from zero (linearly) have the same "absolute value" whether positive or negative.
When adding two rational numbers with different signs the sum will be zero Is this aways sometimes or never true?
sometimes true (when the rational numbers are the same)
What is the role of 0 in rational numbers?
The role of zero(0) in rational numbers is when
How do you Represent irrational number on number line?
The same as you would a rational number. Its distance from zero will represent the number, whether it is rational or irrational.
What are numbers that are the same distance from 0 but in opposite direction?
Negative and Positive numbers. Ex. -4 & 4 are the same distance from zero which is 4.
What are two numbers that are the same distance from zero but are on different sides called?
Opposite numbers.
Can't two different rational numbers have the same absolute value?
Yes, they can. If x is a non-zero rational number then x and -x will have the same absolute value.
Is the set of rational numbers closed under division and Why?
No. Zero is a rational number, but division by zero is not defined.
