19 Equivalent Ratios There are different ways to determine if two ratios (or fractions) are equivalent.

20 Equivalent Ratios There are different ways to determine if two ratios are equivalent. One way is to compare the unit rates. 10 prints for $2; 30 prints for $6 What is a unit rate?

21 Equivalent Ratios

22

23 If the unit rates are the same, the ratios are equivalent.

24 Equivalent Ratios There are different ways to determine if two ratios are equivalent. Another is to the simplified rates. 9 miles in 12 hours; 4 miles in 8 hours. When simplifying a fraction, are we making it larger or smaller?

25 Equivalent Ratios

26

27 If the simplified rates are the same, the ratios are equivalent.

28 Equivalent Ratios There are different ways to determine if two ratios are equivalent. Another is to cross multiply. 25 miles in 3 hours; 32 miles in 4 hours. (If I can’t simplify in my head, this is the method I use.)

29 Equivalent Ratios

31

32

33 If the cross products are the same, the ratios are equivalent.

34 Equivalent Ratios You can use any of these methods.

35 Equivalent Ratios Determine if each pair of ratios or rates are equivalent. Explain your reasoning. 15 out of 20 students; 60 out of 80 students. Do this on your own.

36 Equivalent Ratios

37 Determine if each pair of ratios or rates are equivalent. Explain your reasoning. 5 goals out of 35 attempts; 8 goals out of 40 attempts. Do this on your own.

38 Equivalent Ratios

39 Determine if each pair of ratios or rates are equivalent. Explain your reasoning. 7 correct out of 11 test questions; 6 correct out of 10 test questions. Do this on your own. Use any method.

40 Equivalent Ratios Determine if each pair of ratios or rates are equivalent. Explain your reasoning. 7 correct out of 11 test questions; 6 correct out of 10 test questions. 7 correct ? 6 correct 11 questions = 10 questions 7 x 10 = 70 6 x 11 = 66 70 ≠ 66

41 5 Minute Check Quiz Directions – All answers should be on the right hand side of the paper. I will not look at the left side! You will have 20 minutes to finish the test. Do not forget units, if needed. When complete, bring it to my desk, go back to your desk and work on page 62 and 63 in your book.

42 Equivalent Ratios Agenda Notes Complete page 62 and 63 in your book Homework – No Homework Chapter 1 Test -Friday, Sept 11 Accum Rev 1 due by Sept 11
