Final answer:
The estimation of 300 divided by 15 is exactly 20. Therefore, the student should select option 1) as the correct answer.
Step-by-step explanation:
Estimate 300 by 15. This is a problem involving finding the product of two numbers. The first number, 300, is given, and the second number, 15, is also provided.
To estimate the product, we can use mental math or a calculator to find an approximate answer. Here are some possible estimates:
1) 20: This estimate would result in a product of 6,000 (300 times 20). While this is not an exact answer, it's clear that the estimate is too low.
2) 30: This estimate would result in a product of 9,000 (300 times 30). This estimate is closer to the actual answer, but it's still slightly too low.
3) 40: This estimate would result in a product of 12,000 (300 times 40). This estimate is very close to the actual answer and could be considered a good estimate.
4) 50: This estimate would result in a product of 15,000 (300 times 50). This estimate is slightly higher than the actual answer, but it's still a reasonable estimate.
In summary, estimate number 3, with a value of 40, is the best approximation for finding the product of 300 and 15.
Therefore, the student should select option 1) as the correct answer.
