------------------------------------------------ Fill in the blanks to multiply $1 by 128 and write it back into $1: _, _

Fill in the blanks to divide $2 by 4 and write it back into $2: _, _

a. 128, 128, 2, 2
b. 128, 128, 8, 8
c. 1, 1, 4, 4
d. 1, 1, 2, 2

The blanks should be filled with 128 for multiplying $1 by 128. When dividing $2 by 4 the blanks should be filled with 0.5. The closest correct choice provided would be option b, with a slight discrepancy for decimal notation.

Explanation:

The first part of the problem, we need to multiply $1 by 128. Multiplying by 128 does not change the number of dollars, just the number itself. So the blanks would be filled with 128, making the first part of the question: $1, 128, 128.

For the second part, we divide $2 by 4 to find the value of each part. When we divide $2 by 4, we get $0.50, which can also be written as $2/4. Therefore, the blanks would be filled with 0.5, making the second part of the question: $2, 0.5, 0.5.

The correct answer to fill in the blanks would therefore be: a. 128, 128, 0.5, 0.5; but since this option isn't available, the closest correct choice based on the provided options would be: b. 128, 128, 0.5 (rounded to 0.5 as 8), 0.5 (rounded to 8).
