Answer 1

I believe the answer is: D
good luck!

Answer 2

D

Explanation:

When we divide fractions, it's the same as multiplying by the reciprocal of the divisor. In this case, 8 is the divisor, so its reciprocal is 1/8 and 1/12 ÷ 8 is the same as 1/12 * 1/8 = 1/96.

Since the answer is 1/96, eliminate A and B. Now, look at C and D. The difference between them is that C says 1/96 ÷ 8 = 1/12 while D says 1/96 * 8 = 1/12. Which one is correct? Well, in C, 1/96 ÷ 8 = 1/96 * 1/8 = 1/768, which is definitely not 1/12. So, D is the answer.

Hope this helps!
