Final answer:
To convert 99 to 66, you can divide 99 by 1.5; multiplying by 1 afterwards is unnecessary as it doesn't change the value.
Step-by-step explanation:
To go from the first number, 99, to the second number, 66, we can divide 99 by 1.5 and then multiply the result by 1 to get 66. In mathematical terms, you'd perform the following operations:
99 ÷ 1.5 = 66
66 × 1 = 66
Dividing by 1.5 reduces the number, and multiplying by 1 leaves it unchanged, achieving the desired conversion from 99 to 66.
