Question 71140: Hi, I need help with this problem and I need help getting the answer. Please Help.
To estimate the product of two and seven eights times 39, Jean-Paul multiplied 3 times 40. Would Jean-Paul's estimate be more or less than the actual product?
A.less, because he rounded both numbers down
B. more, because he rounded both numbers down
C. less, because he rounded both numbers up
D. more, because he rounded both numbers up
Answer by Earlsdon(6294)   (Show Source):
You can put this solution on YOUR website! The estimate of 3X40 (= 120) for the actual product of 2 7/8 X 39 (=112 1/8) is more because Jean-Paul rounded both numbers up.
3 is more than 2 7/8
40 is more than 39
