9/10 × 1/12 = (9×1)/(10×12) = 9/120 = (3×3)/(40×3) = 3/40
(10/12) - (1/4) = (10/12) - (3/12) = 7/12
5/6 * 1/10 = 5/60 = 1/12
1 / 12 times 1 / 15 is found by just multiplying 12 times 15. 1 / 12 x 1 / 15 = 1 / 180
2/3 * 12/1 = 8
10/12 + 8/12 = 18/12 or 1 and 6/12 or 3/2 or 1.5
12/1 × 4/9 = 51/3
10 1/3 x 12 = 124
1/4 + 5/6 = 3/12 + 10/12 = 13/12 = 1 and 1/12
1/4 x 12 = three
10/12 minus 2/4 is 1/3
1/12
20/10 × 20/1 = 40/1
