Can you please explain step by step on how to do each of these two problems below? And then tell me whether it involves an arithmetic sequence or a geometric sequence I also need the work shown out on both problems

thank you.

Perform the indicated operations and reduce the answer to lowest terms.

dividion is the reciprocal of multiplication.

-3/4 divided by 5/8=(-3/4)*(8/5)=-6/5

on the second, do the same...

9/14 * 7/3 * 1/2=21/28 check that.

(-3/4) ÷ (5/8)

(-3/4) * (8/5) = -24/20 = -1 4/20 = -1 1/5

(9/14 ÷ 3/7) × ½

[(9/14) * (7/3)] * 1/2

(63/42) * 1/2 = 63/84 = 3/4
