Q. Which expression will give a better estimate of 41.2÷441.2 \div 4?\newlineChoices:\newline(A) 40÷440 \div 4\newline(B) 60÷460 \div 4\newlineUse the expression you picked to estimate the quotient.\newline41.2÷441.2 \div 4 is about \newline\underline{\hspace{2cm}}.
  1. Compare numbers: Compare the numbers 4040 and 6060 to 41.241.2 to see which is closer; 4040 is closer to 41.241.2 than 6060.
  2. Use closer estimate: Use the closer estimate, 4040, to divide by 44. Calculation: 40÷4=1040 \div 4 = 10.
