  1. Learning Goals Gr.6 & 7 – How to Convert Fractions, Decimals & Percent Gr. 8 –Percent Change

  2. Percent Use the percent as the numerator and 100 as the denominator. Then reduce to lowest terms. (Divide the numerator and denominator by their GCF to do this). Multiply by 100 and add a % symbol Decimal Fraction Divide

  3. Sort the following on the number line:1/12, 92%, 0, 1.10, 140%, 39/41 1.10 140% 0 92% 0.2 4/5 50% 39/41 1/12

  4. Grade 6 & 7 Learning 1) Convert the following decimals into fractions, and percent: 0.45, 0.9, 0.0004, 0.111, 1.34 2) Convert the following fractions into percentages and decimals: ¾, 17/10, 1 ½, 63/64, 19/20 3) Convert the following percentages into decimals and fractions: 43%, 100%, 178%, 0.01%, 21.34% 4) Thinking Question: How can you turn a repeating decimal into a fraction? e.g., Convert 0.5 (the 5 keeps repeating) into a fraction .

  5. Percent of Change: The ratio of the amount of increase or decrease to the original amount It is an increase when the new amount is larger than the original and a decrease when the new amount is smaller than the original. To find the percent of change, use the following proportion: Percent of change: Amount of increase or decrease = % Original Amount  100

  6. Find the percent of change (be sure to label your answer as an increase or decrease). Examples: Original amount: 20  Original amount: 40 New amount: 30  New amount: 10 Percent of change=   Percent of change=

  7. Identify the percent of change as an increase or decrease. Then find the percent of change. 1. Original: 45 New: 75 2. Original: 100 New: 42 3. Original: 58 New: 75 66% increase 58% decrease 29% increase

  8. 1) Grade 8 Exit Ticket A book’s original price was $12.99. It is now on sale for $10.99. What is the percent of change? 2) Thinking Question: The percent of change is a 142.5425% (the 425 keeps repeating) increase. What could the original and new amounts be?
