3.8 x 1.7 Give the answer AND explain how you know its reasonable
I will first round the numbers to the nearest whole to get a good estimate. 3.8 is close to 4 and 1.7 is close to 2. My estimate is 4 x 2 = 8. However, I know its going to be a little less than 8 because I rounded both numbers up.
Answer: 6.46
My answer is reasonable because 6.46 is pretty close to my estimate of 8.
