x = 1.4343 -------- (1)
Multiply equation (1) with 100
= > 100x = 100 * 1.4343
= > 100x = 143.43 ----- (2)
subtract (2) from (1), we get
= > 100x - x = 143.43 - 1.43
= > 99x = 142
= > x = 142/99.
Therefore 1.43 bar can be represented in rational number as 142/99.
Hope this helps!
let x be 1.4343
multiply 100 on both the side
100*x=1.4343*100
100x=143.43
100x=142+1.43
100x=142+x
100x-x=142
99x=142
x=142/99
