  1. Estimating Quotients by Rounding
    Estimate the quotient using estimation by rounding. Then, find the exact quotient to check your answer.
    1. 5425\frac{2}{5} ÷ 546\frac{4}{6} =
    2. 4658 ÷ 17 =
    3. 27.83 ÷ 11 =
  2. Estimating Quotients using Compatible Numbers
    Estimate the quotient by rewriting the statement using compatible numbers. Then, find the exact quotient to check your answer.
    1. 3456 ÷ 5 =
    2. 50 ÷ 418\frac{1}{8} =
    3. 5.592 ÷ 6 =
  3. Estimating Quotients with Long Division
    Estimate the quotient using estimation with long division. Then, find the exact quotient to check your answer.
    1. 0.672 ÷ 3 =
    2. 4.265 ÷ 5 =
    3. 16.849 ÷ 83 =
