HELP HOW TO DO THIS EASY EXPLANATION PLS EASYYY I dun have much common sense so pls make it easy.

a) 1 and 4

b) only 1

Step-by-step explanation:

so pretty much look at the fraction. on A its 9/-8 so the fraction is always going to be negative because the -8 is negative and a positive times a negative is a negative. so that means your 9/-8 is going to always ne a negative fraction. that is why the only the fractions that come out to be a negative fraction overall is 1 and 4

now in B, the fraction is -3/-7 so just like in the first one you have negatives but this time you have two. now a negative times a negative is a positive. so your fraction -3/-7 would be positive, thats also why the only correct answer for that question is 1.

(a) 9/-8 = -9/8 = 9-/8, 1 & 4

(b) -3/-7 = 3/7, only 1

its an acute right triangle
