1. EXAMPLE 3 Dividing Mixed Numbers 1 3 6 5 6 –2 = 19 3 17 6 – = 19 3 6 17 – = 19 3 (– 6) 17 – 2 1 Multiply. Divide out common factor. 38 = 17 –, or 4 17 –2 Multiply. Multiply by, the reciprocal of 6 17 –– 3 Check: Use estimation to check your answer. Replace the divisor and dividend with compatible whole numbers. Because 6 (– 3) = – 2, you know that 4 17 –2 is a reasonable answer. Write 1 3 6 5 6 –2 andas improper fractions.
