Given :
- Number line
- AB = BC = CD = DE
- FG = GH = HI = IJ
To Find :
- Rational Number represented by C and I
- Is Rational number represented by H greater than B ?
- Are - 5/4 and -1 1/4 are same ?
- Point that represent 11/4
- point representing greatest number on given number line.
Solution:
Information about Number line:
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
AB = BC = CD = DE
and AB + BC + CD + DE = 1
Hence AB = BC = CD = DE = 1/4
Similarly FG = GH = HI = IJ = 1/4
Rational Number represented by C and I
C = 2 + 2/4 = 2 + 1/2 = 5/2
I = -1 - 3/4 = -7/4
Rational number represented by H is not greater than B as H is on left side of B
Yes , - 5/4 and -1 1/4 are same
-1 1/4 = - 1 - 1/4 = (-4 - 1)/4 = -5/4
D Point represent 11/4
11/4 = (8 + 3)/4 = 2 3/4
point representing greatest number on given number line is E
as E is on right most and represent 3
