Exercise 8.2
Ex 8.2 Class 6 Maths Question 1.
Complete the table with the help of these boxes and use decimals to write the number.
Solution:
Ones  Tenths  Hundredths  Number  
(a)  0  2  6  0.26 
(b)  1  3  8  1.38 
(c)  1  2  8  1.28 
Explanation:
(a) In this figure,
If small block out of 100 are shaded
âˆ´ Decimal representation = 0.26
(b ) 100 small blocks + 38 small blocks are shaded
âˆ´ Decimal representation = 1.38
(c) 100 small blocks + 28 small blocks are shaded
âˆ´ Decimal representation = 1.28
Ex 8.2 Class 6 MathsÂ Question 2.
Write the numbers given in the following place value table in decimal form:
Solution:
(a) 0 Hundreds + 0 Tens + 3 Ones + 2 Tenths + 5 Hundredths + 0 Thousandths
= 3 + 0.2 + 0.05 + 0.000 = 3.250 = 3.25
(b) 1 Hundreds + 0 Tens + 2 Ones + 6 Tenths + 3 Hundredths + 0 Thousandths
= 102.630 = 102.63
(c) 0 Hundreds + 3 Tens + 0 Ones + 0 Tenths + 2 Hundredths + 5 Thousandths
= 0 x 100 + 3 x 10 + 0 x 1 + 0 x \(\frac { 1 }{ 10 }\) + 2 x \(\frac { 1 }{ 100 }\) + 5 x \(\frac { 1 }{ 1000 }\)
= 0 + 30 + 0 + 0.0 + 0.02 + 0.005
= 30.025
(d) 2 Hundreds + 1 Tens + 1 Ones + 9 Tenths + 0 Hundredths + 2 Thousandths
= 2 x 100 + 1 x 10 + 2 x \(\frac { 1 }{ 10 }\) + 0 x \(\frac { 1 }{ 100 }\) + 2 x \(\frac { 1 }{ 100 }\)
= 200 + 10 + 1 + 0.9 + 0.00 + 0.002
= 211 + 0.902 = 211.902
(e) 0 Hundreds + 1 Tens + 2 Ones + 2 Tenths + 4 Hundredths + 1 Thousandths
= 0 x 100 + 1 x 10 + 2 x 1 + 2 x \(\frac { 1 }{ 10 }\) + 4 x \(\frac { 1 }{ 100 }\) + 1 x \(\frac { 1 }{ 1000 }\)
= 0 + 10 + 2 + \(\frac { 2 }{ 10 }\) + \(\frac { 4 }{ 100 }\) + \(\frac { 1 }{ 1000}\)
= 12 + 0.2 + 0.04 + 0.001 = 12.241
Ex 8.2 Class 6 MathsÂ Question 3.
Write the following decimals in the place value table.
(a) 0.29
(b) 2.08
(c) 19.60
(d) 148.32
(e) 200.812
Solution:
(a) 0.29 = 0 + 0.2 + 0.09 = 0 Ones + 2 Tenths + 9 Hundredths
(b) 2.08 = 2 + 0.0 + 0.08
= 2 Ones + 0 Tenths + 8 Hundredths
(c) 19.60 = 10 + 9 + 0.6 + 0.00
= 1 Tens + 9 Ones + 6 Tenths + 0 Hundredths
(d) 148.32 = 100 + 40 + 8 + 0.3 + 0.02
= 1 Hundred + 4 Tens + 8 Ones + 3 Tenths + 2 Hundredths
(e) 200.812 = 200 + 0.8 + 0.01 + 0.002
= 2 Hundreds + 8 Tenths + 1 Hundredth + 2 Thousandths
