Answer : The sum of the given expression is,

Step-by-step explanation :

As we are given the expression:

Let us assumed that,

or,

     ..........(1)

To shifting the one decimal place to the right, we are multiplying the equation by 10 on both side, we get:

      ...........(2)

Now subtracting equation 1 from 2, we get:

      ............(A)

and,

Let us assumed that,

or,

     ..........(1)

To shifting the two decimal place to the right, we are multiplying the equation by 100 on both side, we get:

      ...........(2)

To shifting the one more decimal place to the right, we are multiplying the equation by 10 on both side, we get:

      ...........(3)

Now subtracting equation 2 from 3, we get:

        ............(B)

Now adding equation A and B, we get:

Thus, the sum of the given expression is,

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
