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.
(3/4) ÷ (5/8)
(9/14 ÷ 3/7) × ½

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
