Question

represent 1.23bar in rational form ?

Answer 1

to represent 1.23 in P / Q form




first we take x


x = 1.23 23 23 23 23......



then it's in hundredth place

so we take


100x = 123 . 23 23 23 23


for subtracting ( 1) and ( 2) we get


100x = 123 . 23 23 23 23

- x. = -1 . 23 23 23 23


99x. = 122 .0000


x = 122 / 99


hence answer is 122 /99

Answer 2

Step-by-step explanation:

first we take x

x = 1.23 23 23 23 23......

then it's in hundredth place

so we take

100x = 123 . 23 23 23 23

for subtracting ( 1) and ( 2) we get

100x = 123 . 23 23 23 23

- x. = -1 . 23 23 23 23

99x. = 122 .0000

x = 122 / 99

hence answer is 122 /99
