Question

निम्नलिखत को p/q के रूप में पारदर्शित कीजिए जहा p और q पूर्णाक हो
(1) 0.2555... (2) 0.123

Answer 1

Answer:

(1) 23/90

Step-by-step explanation:

Let x=0.2555....=0.25.....(1)

Multiply equation (1) by 10

∴10x=2.5...(2)

Again multiply equation (2) by 10

∴100x=25.5....(3)

Subtracting (2) from (3), we get

100x-10x=25.5-2.5

90x=23

x=23/90
