To find the height of the stack, we need to multiply the number of blocks by the height of each block.
15 blocks * 1 1/2 inches/block = 22 1/2 inches
So the stack would be 22 1/2 inches tall.
Therefore, the correct answer is 22 1/2 inches.
To find the height of the stack, we need to multiply the number of blocks by the height of each block.
Given that Kris has fifteen 1 1/2 inch blocks, we can calculate the height of the stack as:
15 blocks × 1 1/2 inches/block = 22.5 inches
Therefore, the stack would be 22.5 inches tall.
To solve the problem and find the height of the stack, we need to multiply the number of blocks by the height of each block.
In this case, Kris has fifteen 1 1/2 inch blocks. To find the height of the stack, we multiply 15 (number of blocks) by 1 1/2 inches (height of each block).
First, let's convert 1 1/2 inches to a mixed fraction. To do that, multiply the whole number (1) by the denominator (2), then add the numerator (1). This gives us 3/2 inches.
Now, multiply the number of blocks (15) by the height of each block (3/2 inches):
15 * 3/2 = 45/2 inches
To reduce the answer to lowest terms, we need to simplify the fraction.
The fraction 45/2 can be simplified by dividing the numerator (45) and the denominator (2) by their greatest common divisor, which is 1:
45 ÷ 1 = 45
2 ÷ 1 = 2
So the fraction 45/2 can be reduced to 22 1/2 inches.
Therefore, the stack would be 22 1/2 inches tall.
