12-х=1 1/9

To solve the equation 12-х=1 1/9, we first need to convert the mixed number 1 1/9 to an improper fraction.

1 1/9 as an improper fraction is 10/9.

Now, we rewrite the equation as 12 - x = 10/9.

To solve for x, we need to isolate x on one side of the equation.

Subtract 12 from both sides: 12 - 12 - x = 10/9 - 12 -x = 10/9 - 108/9 -x = -98/9

To get the value of x, multiply by -1 on both sides to make x positive: x = 98/9

Therefore, the solution to the equation 12-x=1 1/9 is x=98/9.
