To solve the equation u - 5/9 = 5/6, you can use the following steps:
Start by adding 5/9 to both sides of the equation:
u - 5/9 + 5/9 = 5/6 + 5/9
Simplifying the left side of the equation:
u = 5/6 + 5/9
Simplifying the right side of the equation:
u = (5/6 + 5/9)
u = (30 + 45) / 54
u = 75 / 54
Simplifying the fraction:
u = 5/4
Therefore, the solution to the equation is u = 5/4
