Answer:
7/12
Step-by-step explanation:
This is a substitution question
We are to substitute the given value in place of the letters
So let's solve
e-1/2f
And e is given to be 15
f is given to be 12
So let's substitute
15-1/2(12)
14/24
Divide both the denominator and numerator by 2
We will have
7/12
So our final answer is 7/12
