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 point
For 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
