Start with zero above the first hashmark on the left. At each hashmark, write the next number up. For example, above the hash mark next to zero, write 1. You can write these in pen as well, so you can re-use the number line over and over again.
A number line is a visual representation of numbers on a straight line. This line is used to compare numbers that are placed at equal intervals on an infinite line that extends on both sides, horizontally or vertically.
An example of a number line is what a math student can use to find the answer to addition and subtraction questions. … A straight line, theoretically extending to infinity in both positive and negative directions from zero, that shows the relative order of the real numbers.
Horizontal line | Vertical line |
---|---|
Parallel to horizon | Perpendicular to horizontal lines |
To mark 1/4; move one part on the right-side of zero. To mark 7/4; move seven parts on the right-side of zero. To mark -3/4; move three parts on the left-side of zero. To mark -9/4; move nine parts on the left-side of zero.
To represent 1/3 on a number line, we divide the gap between O and A into 3 equal parts. Let T and Q be the points of division. Then, T represents 1/3 and Q represents 2/3, because 2/3 means 2 parts out of 3 equal parts as shown below. By using the same procedure, point O represents 0/3 and point A represents 3/3.
For drawing a number line; draw a line of some suitable length and mark points on it so that the line is divided into required equal parts. Mark its middle point as zero. Towards the right of zero, mark the numbers +1, +2, +3,…… etc. at equal distances and towards the left of zero, mark -1, -2, -3,…… etc.
Number lines are a key concept that begins to be used in Grade 2. The length of a line segment with one end placed at zero and the other end of the segment placed on a number represents the magnitude of that number.
There is a sleeping line, the ladder lying flat on the floor and the man lying on the floor. What you see is described as HORIZONTAL. A sleeping line is nothing but a horizontal line. A ladder lying flat is the same as a ladder lying horizontally.
The vertical line in coordinate geometry is a line that goes up to down. In other words, the line that is parallel to the y-axis and has the same x coordinate point is vertical. A vertical line can only be drawn when the line has the same x coordinate.
Represent `8/5` and `(-8)/5` on the number line.
Thus, 2/3 will be placed on the number line between zero and one. Due to the fact that the denominator 3 means that this interval is split into 3 equal sections, we would place 2/3 at the 2nd marker, or 2/3 of the way between zero and 1.
