Parker wants to estimate the product of 12 and 4. He does the Math and gets 48. He wants to check the reasonableness of his answer, so he multiplies 10 by 4 and gets 40. Is Parker’s answer reasonable?
Answer
A
Yes, because his solution answer and estimate answer should be negative.
B
No, because only the answer to his estimation should be negative.
C
No, because 10 is less than 12, so his estimate should be greater than 48.
D
Yes, because 10 is less than 12, so his estimate should be less than 48.
