Answer:
c) 1
Step-by-step explanation:
[tex]\frac{1}{2}[/tex](12·g)-h
g= [tex]\frac{1}{4}[/tex] and h=[tex]\frac{1}{2}[/tex]; substitute back in the equation
[tex]\frac{1}{2}[/tex](12·[tex]\frac{1}{4}[/tex]) - [tex]\frac{1}{2}[/tex]; multiply inside the parenthesis
[tex]\frac{1}{2}[/tex](3)- [tex]\frac{1}{2}[/tex]; multiply and notice the same denominator
[tex]\frac{3}{2}[/tex]-[tex]\frac{1}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1; subtract the fractions
