Final answer:
The expressions simplify to 2, -2, 10, 15, 13, and 11 respectively.
Step-by-step explanation:
The first expression, 10/5, simplifies to 2. To simplify a division expression, we divide the numerator (10) by the denominator (5), which gives us 2. the second expression, -24/12, simplifies to -2. To simplify a division expression with negative numbers, we divide the absolute values of the numbers and apply the negative sign to the result.
The third expression, -20/-2, simplifies to 10. When dividing negative numbers, we multiply the absolute values of the numbers and apply the positive sign to the result. the fourth expression, -300/-20, simplifies to 15. Again, when dividing negative numbers, we multiply the absolute values of the numbers and apply the positive sign to the result. the fifth expression, 65/5, simplifies to 13. Dividing 65 by 5 gives us 13. the sixth expression, -66/-6, simplifies to 11. When dividing negative numbers, we multiply the absolute values of the numbers and apply the positive sign to the result.
