Question

Express 2.543434------- in the form of p/q where p is not equal to 0.

Answer 1

let the no.= x
hence x=2.543434--------- 1
multiply 10 on both sides
10*x=2.543434*10
10x=25.3434--------2
subtracting 1 from 2 we get
10x-x=25.3434-2.53434
9x=the answer u get
x= the answer you get/9
that is in the form of p/q

Answer 2

X=2.543434.........
100x =254.3434.....
Multiply by 10,000 in both sides......
10000x=25434.3434......
10,000x-100x=25434.3434...-254.3434...
9900x=25180
X=25180/9900

Hope it helps u......
