Express each of the following decimal in the 𝑝𝑞 form.
(i) 0.57 (ii) 0.176 (iii) 1.00001 (iv) 25.125
Solution:
(i) 0.57 = 57100 (∵ two digits are there after the decimal poing)
(ii) 0.176 = 1761000
(iii) 1.00001 = 100001100000
(iv) 25.125 = 251251000

Question 2.
Express each of the following decimals in the rational form 𝑝𝑞
(1) 0.9⎯⎯⎯
(ii) 0.57⎯⎯⎯⎯⎯⎯
(iii) 0.729⎯⎯⎯⎯⎯⎯
(iv) 12.28⎯⎯⎯
Solution:
(i) 0.9⎯⎯⎯
Let x = 0.9⎯⎯⎯
⇒ x = 0.999 ………………. (1)
Here periodicity is 1. So, equation (1) should be multiplied both sides with
= 10 × x = 10 × 0.999
10 x = 9.999 ………….. (2)

0.9⎯⎯⎯ = 1

Second Method:
0.9⎯⎯⎯=0+9⎯⎯⎯=0+99
= 0 + 1 = 1

(ii) 0.57⎯⎯⎯⎯⎯⎯
x = 0.57⎯⎯⎯⎯⎯⎯ ⇒ x = 0.5757…………(1)
Here periodicity is 2. So, we should multiply with 100
⇒ 100 × x = 100 x 0.5757 …………..
100 × =57.57 ……………………. (2)

(iii) 0.729⎯⎯⎯⎯⎯⎯
x = 0.729⎯⎯⎯⎯⎯⎯
x = 0.729⎯⎯⎯⎯⎯⎯ ⇒ x = 0.7979…………(1)
Here periodicity is 2. So, equation (1) should multiply with 100
⇒ 100 × x = 100 × 0.72929 …………..
100 × = 72.929 …………………… (2)

(iv) 12.28⎯⎯⎯
x = (iv) 12.28⎯⎯⎯
⇒ x = 12.288 ………..(1)
Here periodicity is 1. So, equation (1) should multiply with 10
⇒ 100 × x = 100 × 12.288 …………..
10 x = 122.888 …………………… (2)

Question 3.
Find(x + y) ÷ (x – y) if
(i) x = 52, y = −34
(ii) x = 14, y = 32
Solution:
If x = 52, y = −34 then

ii) x = 14, y = 32

Question 4.
Divide the sum of −135 and 127 by the product of −137 and −12
Solution:
Sum of −135 and 127

the product of −137 and −12

Question 5.
If 25 of a number exceeds 17 of the same number by 36. Find the number.
Solution:
Let the number be ‘x’ say.
25 part of x = 25 × x = 2𝑥5
17 part of x = 17 × x = 𝑥7
∴ According to the sum,

Question 6.
Two pieces of lengths 225 m and 3310 mare cut off from a rope 11 m long. What is the length of the remaining rope?
Soltuion:
The length of the remaining rope

The cost of 723 mts (233 mts ) of cloth
= ₹ 1234 = ₹ 514
∴ The cost of 1m cloth
= 514÷233=514×323=15392 = ₹ 1.66

Question 8.
Find the area of a rectangular park which is 1835m long and 823 in broad.
Solution:
The length of the rectangular park
= 1835m = 935
Its width / breath = 823 m = 263 m
