gregory estimated the product of two decimals to be 24. which could be the two decimals? 2.07(10.3) 4.02(6.8) 2.74(7.1) 5.9(3.92)
Answer
Explanation:
Step1: Estimate 2.07(10.3)
Round 2.07 to 2 and 10.3 to 10. Then $2\times10 = 20$.
Step2: Estimate 4.02(6.8)
Round 4.02 to 4 and 6.8 to 7. Then $4\times7=28$.
Step3: Estimate 2.74(7.1)
Round 2.74 to 3 and 7.1 to 7. Then $3\times7 = 21$.
Step4: Estimate 5.9(3.92)
Round 5.9 to 6 and 3.92 to 4. Then $6\times4=24$.
Answer:
5.9(3.92)
