Section 3-3 “Dividing Decimals” By multiplying both numbers by the same power of ten, you can make the divisor an integer. Dividing by an integer is much easier than dividing by a decimal. How do you divide two decimal numbers 0.6 ÷ divisor or 3 6 Multiply both numbers by 10 2

Find the quotient of ÷ Finished Move the decimal point straight up, then divide as you normally would Multiply both numbers by 100 to make the divisor an integer

Find the quotient of 7.75 ÷ Finished Move the decimal point straight up, then divide as you normally would Multiply both numbers by 100 to make the divisor an integer 0

“Dividing Integers” Rule #1 The quotient of two integers with the same sign is always POSITIVE! 8 ÷ 2 = ÷ (-3) = 6 Rule #2 The quotient of two integers with different signs is always NEGATIVE! -6 ÷ 3 = ÷ (-4) = -7 Remember this?

Negative or Positive? Without solving the problem, decide whether the quotient will be positive, negative, or zero. Then estimate the answer to the nearest integer. Without solving the problem, decide whether the quotient will be positive, negative, or zero. Then estimate the answer to the nearest integer ÷ (-4.36) positive ÷ negative -3.3 ÷ 3.3 negative ÷ (-6.02) positive
