  1. Comparing Fractions • Using Percents Kim Kneipp 5th Grade Math EDT6005

  2. Comparing Fractions • To compare fractions we can: • Find a least common denominator • Use Decimals • Use Percents

  3. Today... • We will be learning how to compare fractions... • USING PERCENTS!

  4. How do I find a fraction’s percent? STEP 1 • Start with your given fraction/fractions Example

  5. Step 2 In your calculator, divide the numerator by the denominator Example

  6. Step 3 This number is the decimal equivalent to the fraction Example

  7. Step 4 Multiply the decimal by 100 and there is your percent! Example

  8. Last but not least… • Compare the two percents, the bigger percent, is the bigger fraction Example

  9. For example... • 3 4= 0.75 • 0.75 x 100= 75 or 75%

  10. Inequality signs • Greater than: > • Less than: < • Equal to: = • Remember the open side of the sign, points to the bigger number • example: 10 > 4

  11. What do I compare? • Find the decimal and percent for each fraction • Once you do this, see which percent is the biggest. • Place the <, >, or = sign between the fractions

  12. Let’s see how this works…

  13. Example: Which is greater 5/8 or 6/10? Back

  14. Find the Decimal Equivalent • 5 ÷ 8= 0.625 • 6 ÷ 10 = 0.60 Back

  15. Find the percent.. • 0.625 x 100= 62.5% • 0.6 x 100= 60% Back

  16. so... • 62.5 % > 60% • SO: • \ Back
