15
22 times, with 4 left over.
8/15 x 9/4 = 1 1/5
8/9 × 15/28 × 21/25 = (8×15×21)/(9×28×25) = 2520/6300 = (2×1260)/(5×1260) = 2/5
4/15 * 9/5 = 4/5 * 3/5 = 12/25
2/9 × 4/15 = 8/135
9/25
15
22 times, with 4 left over.
8/15 x 9/4 = 1 1/5
8/9 × 15/28 × 21/25 = (8×15×21)/(9×28×25) = 2520/6300 = (2×1260)/(5×1260) = 2/5
15 goes into 129 8.6 times or 8 with 9 left over.
15 times 9 is 135
4/15 * 9/5 = 4/5 * 3/5 = 12/25
The product is 45/105 or 9/35 after simplification.
8/9 * 3/10 = 4/15
2/9 = 30/135 4/15 = 36/135 Total = 66/135, which simplifies to 22/45.
