Final answer:
The new dimensions of the sheet of paper, after being reduced to 75% of its size, are approximately 6.375 inches by 8.25 inches.
Step-by-step explanation:
To find the new dimensions of the sheet of paper after it has been reduced to 75% of its size, we need to multiply the original dimensions by 0.75. The original dimensions are 8.5 inches by 11 inches. Multiplying each dimension by 0.75, we get:
New width: 8.5 inches x 0.75 = 6.375 inches
New height: 11 inches x 0.75 = 8.25 inches
Therefore, the new dimensions of the sheet of paper are approximately 6.375 inches by 8.25 inches.
