To multiply fractions, multiply the numerators and multiply the denominators.
Multiply the numerators: 23 * 12 = 276. Multiply the denominators: 45 * 55 = 2475.
Thus, 23/45 * 12/55 = 276/2475 = 4/35.
Multiply the numerators: 9 * 7 = 63. Multiply the denominators: 14 * 18 = 252.
Thus, 9/14 * 7/18 = 63/252 = 1/4.
Multiply the numerators: 11 * 5 = 55. Multiply the denominators: 13 * 8 = 104.
Thus, 11/13 * 5/8 = 55/104.
Multiply the numerators: 17 * 8 = 136. Multiply the denominators: 24 * 35 = 840.
Thus, 17/24 * 8/35 = 136/840 = 17/105.
Multiply the numerators: 3 * 11 = 33. Multiply the denominators: 5 * 9 = 45.
Thus, 3/5 * 11/9 = 33/45 = 11/15.
Multiply the numerators: 5 * 6 = 30. Multiply the denominators: 7 * 11 = 77.
Thus, 5/7 * 6/11 = 30/77.
Multiply the numerators: 4 * 2 = 8. Multiply the denominators: 9 * 5 = 45.
Thus, 4/9 * 2/5 = 8/45.
Multiply the numerators: 6 * 5 = 30. Multiply the denominators: 17 * 6 = 102.
Thus, 6/17 * 5/6 = 30/102 = 5/17.
Multiply the numerators: 12 * 3 = 36. Multiply the denominators: 13 * 4 = 52.
Thus, 12/13 * 3/4 = 36/52 = 9/13.
Multiply the numerators: 10 * 5 = 50. Multiply the denominators: 17 * 8 = 136.
Thus, 10/17 * 5/8 = 50/136 = 25/68.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
