One.
7/6 times 1/2 = 7/12
It is: 3/7 times 4/6 = 2/7 in its lowest terms
5/6 times 7/8 is 35/48
6*(6/7) = 6*6/7 = 36/7 or 51/7.
6/9 * 7/6 = 1/9 * 7/1 = 7/9
(4/3)*(6/7) = 8/7
(7/8) * (1/6) = (7*1)/(8*6) = 7/48
12/7 × 5/6 = 10/7 or 13/7
22/7 × 6/1 = 132/7 or 186/7
4/5*6/7 = (4*6)/(5*7) = 24/35
7/24 * 6/21 = 1/12
28 * 6/7 = 4 * 6/1 = 24
