Exercise 7.5                                                                              page: 7.20
1. Fill in the blanks by using > or < to complete the following:
(i) 25.35 …… 8.47
(ii) 20.695 …… 20.93
(iii) 0.39 ……. 0.72
(iv) 0.109 ……. 0.83
(v) 0.236 ……. 0.201
(vi) 0.93 ……. 0.99
Solution:

(i) 25.35 …… 8.47
We know that the whole numbers 25 > 8
Hence, 25.35 > 8.47.

(ii) 20.695 …… 20.93
We know that both the whole numbers are equal
So by checking the tenth parts we know that 9 > 6
Hence, 20.695 < 20.93.

(iii) 0.39 ……. 0.72
We know that both the whole numbers are 0
So by checking the tenth parts we know that 7 > 3
Hence, 0.39 < 0.72.

(iv) 0.109 ……. 0.83
We know that both the whole numbers are 0
So by checking the tenth parts we know that 1 < 8
Hence, 0.109 < 0.83.

(v) 0.236 ……. 0.201
We know that both the whole numbers are 0
So by checking the hundredth parts we know that 3 > 0
Hence, 0.236 > 0.201.

(vi) 0.93 ……. 0.99
We know that both the whole numbers are 0
So by checking the hundredth parts we know that 3 < 9
Hence, 0.93 < 0.99.

(i) 1.008 or 1.800
(ii) 3.3 or 3.300
(iii) 5.64 or 5.603
(iv) 1.5 or 1.50
(v) 1.431 or 1.439
(vi) 0.5 or 0.05
Solution:

(i) 1.008 or 1.800

(v) 0.236 ……. 0.201
(vi) 0.93 ……. 0.99
Solution:

(i) 25.35 …… 8.47
We know that the whole numbers 25 > 8
Hence, 25.35 > 8.47.

(ii) 20.695 …… 20.93
We know that both the whole numbers are equal
So by checking the tenth parts we know that 9 > 6
Hence, 20.695 < 20.93.

(iii) 0.39 ……. 0.72
We know that both the whole numbers are 0
So by checking the tenth parts we know that 7 > 3
Hence, 0.39 < 0.72.

(iv) 0.109 ……. 0.83
We know that both the whole numbers are 0
So by checking the tenth parts we know that 1 < 8
Hence, 0.109 < 0.83.

(v) 0.236 ……. 0.201
We know that both the whole numbers are 0
So by checking the hundredth parts we know that 3 > 0
Hence, 0.236 > 0.201.

(vi) 0.93 ……. 0.99
We know that both the whole numbers are 0
So by checking the hundredth parts we know that 3 < 9
Hence, 0.93 < 0.99.

(i) 1.008 or 1.800
(ii) 3.3 or 3.300
(iii) 5.64 or 5.603
(iv) 1.5 or 1.50
(v) 1.431 or 1.439
(vi) 0.5 or 0.05
Solution:

(i) 1.008 or 1.800

We know that the whole numbers are equal
So by comparing tenths place we know that 0 < 8
Hence, 1.008 < 1.800.

(ii) 3.3 or 3.300
We know that the whole numbers and tenths place are equal
Hence, 3.3 = 3.300.

(iii) 5.64 or 5.603
We know that the whole numbers are equal
So by comparing the hundredths place we know that 4 > 0
Hence, 5.64 > 5.603.

(iv) 1.5 or 1.50
We know that the whole numbers and tenths place are equal
Hence, 1.5 = 1.50.

(v) 1.431 or 1.439
We know that the whole numbers are equal
So by comparing thousandths place we know that 1 < 9
Hence, 1.431 < 1.439.

(vi) 0.5 or 0.05
We know that the whole numbers are equal
So by comparing tenths place we know that 5 > 0
Hence, 0.5 > 0.05.
