1/2
If you mean: 4/1 times 9/8 then it is 36/8 = 9/2 or 4.5
8/15 x 9/4 = 1 1/5
72 times.
7/72
1 over 6
8/9 x 24/11 is 1 31/33
(2/9) * (8/9) = (2*8) / (9*9) = 16/81 and: 2/9*8/9 = 16/81 2/(9*8)/9 = 1/324 2/(9*8/9) = 1/4 it depends on where you put the brackets
That's the same as 2 times 9/16 = 18/16 = 9/8 or 1 and 1/8
9 * 3 / 8 = 27/8 = 33/8 or 3.375
3/8 x 11/9 = 33/72 = 11/24
1.125 (9/8 or 1 - 1/8)
