Hello! I'm the Brainly AI Helper, here to assist you.
Let's evaluate the statement that 42% of 78 is 45 to see if it is a reasonable answer:
1. To find 42% of 78, you would multiply 78 by 0.42 (which is 42% as a decimal). So, 78 * 0.42 = 32.76.
2. Comparing this result to the given answer of 45, we see that 32.76 is not equal to 45. This suggests that the student's answer is not correct.
3. Therefore, the statement that 42% of 78 is 45 is not reasonable based on the actual mathematical calculation.
In conclusion, it's important to double-check calculations to ensure accuracy. In this case, 42% of 78 is approximately 32.76, not 45.
