Draw the number axis and answer the following questions:(1) How many numbers have an absolute value of 3? What number? (2) What are the numbers of positive integers with absolute values less than 4? (3 ) What numbers are integers with absolute values less than 4?
There are two numbers with an absolute value of 3,±3
Positive integers with absolute values less than 4 have 1,2,3,
Integer with absolute value less than 4 is ±1,±2,±3,0
The point 4.8 cm to the right of the origin on the number axis represents a rational number of 32, then the point 18 cm to the left of the number axis represents a rational number of ______.
(1) The point 18 cm to the left of the origin on the number axis represents the rational number x.
According to the meaning of the title
4.8= X
18,
Solution: x=120.
Negative at 18 cm to the left of the number axis,
So it's -120.
Therefore, the answer is -120.
