Answer:
To solve the equation Z - 2/5=1/3, we need to get Z alone on one side of the equation.
First we add 2/5 to both sides of the equation to get
Z - 2/5 + 2/5 = 1/3 + 2/5
Z = 1/3 + 2/5
To combine the fractions on the right side of the equation, we need to find a common denominator.
The common denominator of 1/3 and 2/5 is 15
So we can convert 2/5 to 9/15
Z = 1/3 + 9/15
Now we can add the fractions
Z = 12/15 + 9/15
Z = 21/15
So the solution to the equation is Z = 21/15
