1.)Locate 0.4 on a number line. The decimal 0.4 is equivalent to 410 , so 0.4 is located between 0 and 1 . On a number line, divide the interval between 0 and 1 into 10 equal parts and place marks to separate the parts.
2.)Represent the following decimals 0.9, -1.3, -0.6 and 1.1 on a number line. To mark 0.9; move nine parts on the right-side of zero. To mark -1.3; move thirteen parts on the left-side of zero. To mark -0.6; move six parts on the left-side of zero.
3.)To mark 0.7; move seven parts on the right-side of zero. To mark -0.4; move four parts on the left-side of zero. To mark -1.2; move twelve parts on the left-side of zero. The following diagram shows markings of decimals 0.3, 0.7, -0.4 and -1.2 on a number line.
4.)Represent 0.8 on the number line. Solution: As we know, the number 0.8 is equivalent to 8 tenths, so we divide the section between 0 and 1 into 10 equal parts. Now, stepping 8 points from 0 towards 1 gives us 0.8.
5.)If you were asked to show 0.3 on the number line, we would put a dot on three tenths.
