Decimals in number line - 1 decimal point For numbers with 1 decimal point like 4.2 We draw it in the number line Now, 4.2 > 4 & 4.2 > 5 So, we draw number line from 4 to 5 We divide number line between 4 & 5 in 10 equal parts Draw 28.7 on number line Now, 28.7 > 28 & 28.7 < 29 So, 28.7 lies between 28 & 29 We draw number line from 28 & 29 We divide the number line between 28 & 29 in to 10 equal parts Decimals in number line - 2 decimal pointFor numbers with 2 decimal point like 2.83 We draw it in the number line Now, 2.83 > 2 & 2.83 > 3 So, we draw number line from 2 to 3 We divide number line between 2 to 3 in 10 equal parts Now, 2.83 will lie between 2.8 & 2.9 We divide it into 10 equal parts Draw 48.85 in number line Now, 48.85 > 48.8 & 48.85 > 48.9 So, we draw number line from 48.8 to 48.9 We divide the number line between 48.8 & 48.9 into 10 equal parts
