8/9 × 15/28 × 21/25 = (8×15×21)/(9×28×25) = 2520/6300 = (2×1260)/(5×1260) = 2/5
8/15 x 9/4 = 1 1/5
7/8 x 6/35 x 5/9 = (7×6×5)/(8×35×9) = 1/12 ≈ 0.083333
(4/5)*H = 8/9Multiply each side by the recoprical of H's coefficient(5/4)*(4/5)*H = (8/9)*(5/4)H = 40/36H = 10/9, or 1.111

3/5 times 3/8 = 9 steps:1- get the denominator with the same number, so you have to times 5 by 8 and 3 by 8. Then you times 5 by 8 and 3 by 5. 2- Your denominator will be 40.so you will get 15/40 times 24/403. keep the denominator which is 40 and multiply the top 15 times 24 which equals 360.4- now you have 360/40, now simplify.5- you will get 9.
8/9 minus 5/9 is 1/3
(4/5)*H = 8/9Multiply each side by the recoprical of H's coefficient(5/4)*(4/5)*H = (8/9)*(5/4)H = 40/36H = 10/9, or 1.111
4/5 x 5/6 = 20/30 or 2/3 2/3 x 9/8 = 18/24 or 3/4
