represent 1.5 on the number line
Answers
Answer:
To represent a decimal number on a number line, we divide the unit length between 0 and 1 into 10 equal parts. Between any two integers, for example, 1 and 2 we have 1.1, 1.2. 1.3, 1.4, 1.5, 1.6, 1.7, 1.8 and 1.9. So if we have to mark we can mark it between 1 and 2 using a ruler.

Problem : Locate 1.6 on the number line.
Solution :
We first see that 1.6 is located between the numbers 1 and 2.
Then, the unit length between 1 and 2 is divided into ten equal parts.
Lastly, 1.6 is located.
Problem: Write the following as numbers in the given table.
Solution :
There are 3 whole blocks, one block and 2 one tenth portions.
So we get = 3*10 + 1*1 + 2*1/10 = 30 + 1+0.2
= 31.2
Problem: Write as decimals: Seven-tenths
Solution :
= 7*1/10 = 7/10
=0.7
Problem: Write as decimals: Two tens and nine-tenths
Solution :
=2*10 + 9*1/10
=20 + 0.9
=20.9
Problem: Show the following numbers on the number line. 1.9
Solution :
Firstly, it is seen that 1.9 is located between 1 and 2.
The block between 1 and 2 is divided into ten equal parts.
1.9 is marked on the number line.
Problem: Show the following numbers on the number line. 2.5
Solution :
Firstly, it is seen that 2.5 is located between 2 and 3.
The block between 2 and 3 is divided into ten equal parts.
2.5 is marked on the number line.
