Mario estimated the product of 132.4 × 27.9 in two different ways, as shown below. Using compatible numbers: 132.4 times 27.9 almost equals 130 times 30 = 3,600. Rounding to the nearest whole number: 132.4 times 27.9 almost-equals 132 times 28 = 3,696. Find the exact product. What can you say about Mario’s estimates? Check all that apply. Using compatible numbers gave an answer closer to the exact answer. Rounding to the nearest whole number gave an answer closer to the exact answer. Both methods gave a reasonable estimate for the exact answer. Mario made errors in both estimates, so neither is reasonable.
