**NCERT Solutions for Class 6 Maths Chapter 8 Decimals Ex 8.2**

**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

∴ Decimal representation = 0.26

(b ) 100 small blocks + 38 small blocks are shaded

∴ Decimal representation = 1.38

(c) 100 small blocks + 28 small blocks are shaded

∴ Decimal representation = 1.28

Ex 8.2 Class 6 Maths 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 + 2 x + 5 x

= 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 + 0 x + 2 x

= 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 + 4 x + 1 x

= 0 + 10 + 2 + + +

= 12 + 0.2 + 0.04 + 0.001 = 12.241

Ex 8.2 Class 6 Maths 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

The above information, we can gives in place value Table:

Hundreds(100) | Tens(10) | Ones(1) | Tenths(1/10) | Hundredths(1/100) | Thousandths(1/1000) | |

(a) | 0 | 0 | 0 | 2 | 9 | 0 |

(b) | 0 | 0 | 2 | 0 | 8 | 0 |

(c) | 0 | 1 | 9 | 6 | 0 | 0 |

(d) | 1 | 4 | 8 | 3 | 2 | 0 |

(e) | 2 | 0 | 0 | 8 | 1 | 2 |
