To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
9. To divide 5/6 by 1/3, we need to find the reciprocal of 1/3, which is 3/1. Then, we multiply 5/6 by 3/1: (5/6) * (3/1) = (5 * 3) / (6 * 1) = 15/6. However, we can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3. This gives us 5/2.
11. To divide 1/2 by 3/5, we need to find the reciprocal of 3/5, which is 5/3. Then, we multiply 1/2 by 5/3: (1/2) * (5/3) = (1 * 5) / (2 * 3) = 5/6.
13. To divide 7/12 by 5/6, we need to find the reciprocal of 5/6, which is 6/5. Then, we multiply 7/12 by 6/5: (7/12) * (6/5) = (7 * 6) / (12 * 5) = 42/60. Once again, we can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 6. This gives us 7/10.
