Answer:
Hey there! your answer should be the first choice, -1/8
Step-by-step explanation:
multiplication and division in fraction are way easier than adding and subtracting them since you don't have to use factoring much.
so first you set them aside
then, literally just multiply them across.
meaning, top times top a.k.a. the numerator and bottom times bottom a.k.a. the denominator
check this little cheat code
positive x positive = positive
negative x negative = positive
positive x negative = negative
negative x positive = negative
so lets do the top, the numerators first: 1 x (-1) = -1
then the bottom, the denominators next: 2 x 4 = 8
now replace your answer with that and you get which leads you with the first answer choice.
I hope this helps! :)
