Answer:
6 times 1.5 equals 9. Essentially, this is just 1 and a half of 6, meaning you have 6, and half of 6, 3, together.
12 times 0.25 equals 3. Multiplying something by 0.25 has the same effect as dividing by 4, as both results in a quarter of the original number. Since 3 is a quarter, or 1/4 the size of 12, that means that multiplying it by 1/4 or 0.25 will give us 3.
