Question

Express 3.145(bar on 45) in form of p/q​

Answer 1

let x= 3.145

multiplying both sides by 10

10x = 31.45 ( mark this 1)

now multiplying both sides by 100 in equation 1

1000x = 3145.45 ( mark this 2)

subtracting equation 1 from 2

1000x-10x = 3145.45-31.45

990x = 3114.00

x = 3114/990.

if u want u can simplify.
