Question

change the number into p by q form 1.214 bar for 14

Answer 1

let x= 1.214141414........... ----(1)

periodicity is 2

multiply with 100 on both sides

then 100x=121.41414.....----(2)

(2)-(1) gives

99x= 120.2

x=1202/990


I hope this will help u :))

Answer 2

let x= 1.2141414.....---(1)
multiply (1) with 10
10x=12.141414......-----(2)
Multiply (2) with 100
1000x= 1214.141414.....(3)
subtract (2) from (3)
990x = 1202
x=1202/990
x= 601/495
=p/q form
