Answer 2

Solving the Equation

To solve the equation, we need to find the value of x when adding it to 11/15 and then adding 0.4 results in 1 1/5.

Let's denote the value of x as X.

The equation can be represented as: X + 11/15 + 0.4 = 1 1/5

Solution

To find the value of X, we can start by subtracting 11/15 and 0.4 from 1 1/5.

1 1/5 - 11/15 - 0.4 = X

Calculating the Result

1 1/5 is equal to 6/5.

So, the equation becomes: 6/5 - 11/15 - 0.4 = X

Simplifying the Equation

To simplify the calculation, we can convert all the fractions to have a common denominator.

6/5 = 18/15

So, the equation becomes: 18/15 - 11/15 - 0.4 = X

Final Calculation

Now, we can perform the subtraction to find the value of X.

18/15 - 11/15 - 0.4 = X 7/15 - 0.4 = X 7/15 - 6/15 = X 1/15 = X

Conclusion

Therefore, the value of X is 1/15.

X = 1/15
