  1. Tuesday, October 18th Warm Up Please take out homework and complete warm up Did you write down your homework? Show the absolute value of 4 on the number line Find the product

  2. Schedule for the Week Tuesday: Dividing fractions and decimals Wednesday: (sub) multiplying and dividing fractions word problems * study guide Thursday: (field trip) Review Study guide, Witches Brew due Friday: • Teacher Project DUE-present Projects • x and ÷ decimals due • Weekly review due MONDAY IS TEST

  3. A little Riddle…. “Line up your decimals, add in your zeroes, find the sum, don’t be a bum…..line up your decimals, add in your zeroes, now it’s time to subtract, don’t get this out of wack”

  4. Dividing Decimals • 1. Set up divisor and dividend correctly • 2. Look at the Divisor, move decimal place over to make a • whole number • 3. However many places you moved the decimal in step 2, you • move the decimal in the dividend • 4.Divide as you would with a whole number

  5. Just Watch 1.80 ÷ .06

  6. HomeworkAnswers Complete your assigned number on your whiteboard

  7. Multiplication Extentionon own notes

  8. Multiplying Mixed Numbers YOU HAVE TO MAKE BOTH FRACTIONS INTO IMPROPER FRACTIONS

  9. 1 __ 5 6 __ 5 1 • 5 + 1 _________ Remember! 5 To write a mixed number as an improper fraction, start with the whole number, multiply by the denominator, and add the numerator. Use the same denominator. = = 1

  10. 1 __ Write 1 as an improper fraction. 1 = • 1 4 1 1 1 4 1 • 4 4 1 __ __ __ __ __ __ __ __ _____ 3 12 3 3 4 • 3 3 3 3 4 4 Let’s Try Together! • 1 Multiply numerators. Multiply denominators. Write the answer in simplest form.

  11. You try! a. b.

  12. Todays Mission Dividing fractions

  13. Who remembers?

  14. KFC Keep Flip Change

  15. Word of the Day Reciprocals can help you divide by fractions. Two numbers are reciprocals if their product is 1.

  16. Find the Reciprocal of each number • 5

  17. 1. The Recipe • Keep your first fraction the way it is • “Flip” (find the Reciprocal) the second fraction • Change problem to multiplication • Reduce diagonally if possible • Multiply Numerator • Multiply Denominator

  18. Rewrite as multiplication using the reciprocal of 7, . 8 8 • 1 8 1 1 8 8 __ __ __ __ __ ____ __ 7 7 7 7 • 7 7 7 49 Just Watch ÷ 7 ÷ 7 = • = Multiply by the reciprocal. = The answer is in simplest form.
