ANSWER CORRECTLY FOR BRANILIST ANSWER ​

Answer 1

Answer:

option c

-9/16 is correct answer

Answer 2

Correct answer is (c)

Explanation:

a) -12/26

This is not in the standard form, as it can be further simplified by dividing numerator and denominator by 2, to get -6/13. Now, as -6 and 13 are co-prime, we can say that it is in standard form

b) -49/91

Same reasoning, can be reduced to -7/13 (divide both by 7)

c) -9/16

9 and 16 are coprime, so this fraction is in standard form

d) 28/-105

Same reasoning, can be reduced to 4/-15 (or -4/15)
