Final answer:
To estimate the quotient 32.4 ÷ 3, round the numbers to the nearest whole number and divide. The answer is about 10.7.
Step-by-step explanation:
To estimate the quotient 32.4 ÷ 3, we can use rounding. Both 32.4 and 3 have one decimal place. By rounding 32.4 to the nearest whole number, we get 32. Then, rounding 3 to the nearest whole number, we get 3. Now, we can divide 32 by 3, which gives us an estimate of 10.7. So, 32.4 ÷ 3 is about 10.7.
This estimation is reasonable because rounding the numbers to the nearest whole number doesn't introduce a significant error in the result. It provides a quick and approximate answer that is close to the actual quotient.
