I'll be glad to check your answer.

1.5 ???

No.

What is 11/2?

To calculate the number of 1/4 cups needed to get 11/2 cups of sugar, you can follow these steps:

Step 1: Convert 11/2 cups into quarters.
To do this, consider that there are 2 quarters in a half. Multiply the number of half cups by 2:
11/2 * 2 = 11/1 * 1/2 * 2 = (11 * 1 * 2) / (1 * 2) = 22/2 = 11 quarters.

Step 2: Determine the number of 1/4 cups in 11 quarters.
Since there are 4 quarters in 1 cup, divide 11 quarters by 4:
11/4 = 2 remainder 3.

Step 3: Combine the whole number and the remainder.
The whole number represents the complete 1/4 cups, and the remainder indicates the extra 1/4 cup needed. Therefore:
2 (whole number) + 1/4 (remainder) = 2 1/4 cups.

Thus, they should measure 2 and 1/4 cups of sugar using 1/4 cups to get a total of 11/2 cups.
