24. Student Debrief (10 minutes) 4.221 7 = ______. Explain how you would decompose 4.221 so that you only need knowledge of basic facts to find the quotient. Correct all dividends in #4 so that the quotients are correct. Is there a pattern to the changes that you must make? In 4a, what mistake is being made that would produce 5.6 7 = 8 When decomposing decimals in different ways, how can you tell which is the most useful? Is there another decomposition of the dividend in 2c that could have been useful in dividing by 2? What about in 2d? Why or why not? In 2a, how does your understanding of whole number division help you solve the equation with a decimal?
