Answer:
Step-by-step explanation:
(1) 3 1/4 = 13 / 4
(13 / 4) / 2 = 13 / 8 = 1 5/8
(2) (1 / 7) / (2 / 5) = (1 * 5) / ( 2 * 7) = 5 / 14
5 / 14 - 1 / 7 = 5 / 14 - 2 / 14 = 3 / 14
(3) 6 1/2 = 13 / 2 and 3 2/3 = 11/3
(13 /2) / (11 / 3) = (3 * 13) / (2 * 11) = 39 / 22 = = 1 17/22
(4) 3 1/5 = 16 / 5
16 / 5 * 5 / 8 = 80 / 40 = 2
(5) 2 3/4 = 11 / 4
the reciprocal is 4 / 11
