Answer 2

Answer:

the answer is 4121/999

Step-by-step explanation:

Let us take x=4.125125........ -(1)

Let us multiply the above equation with 1000

1000x=4125.125125..... -(2)

Subtract (1) from (2)

We get 999x=4121(All decimal places behind the whole no value gets cancelled.You cannot multiply with 10 or 100 because when subtracting ,behind the decimal value 5125125....-125125..... is not equal to zero due to which the recurring decimals do not get cancelled and yet remain.)
