Question

Evaluate e-1/2f when e=15 and f=12

Answer 1

Explanation:

e/4+2f-3 when c=12and f=1/2

Answer 2

7/12

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
