Transcript

  • 1. Round Decimals Mrs. Young EMC 1
  • 2. How do I round decimals???
    • Rounding decimals
      • Very similar to rounding whole numbers – the only difference is that there is a decimal point!
      • Look at the digit to the right of where you are rounding
        • If the digit is 4 or less, round down
        • If the digit is 5 or more, round up
  • 3. Rounding Decimals
    • Round to the nearest hundredth
      • 6.2 7 8
      • The number to the right of the 7 is an 8
        • 8 is greater than five so I need to round up!
        • The 2 becomes a 3 and everything else becomes a 0
        • 6.278 rounded to the nearest hundredth equals 6.300
  • 4. More on Rounding Decimals
    • Round to the nearest tenth
    • 4. 0 82
    • The number to the right of 0 is 8
    • 8 is greater than 0, which means that I need to round the 0 up to a 1
    • All numbers after the 1 will become a 0
    • The answer is 4.100
  • 5. More practice!
    • Round to the nearest hundredth
    • 0.5 5 1
      • The number to the right of the 5 is 1
        • 1 is less than four so I need to round down!
        • The 5 stays as a 5 and everything else becomes a 0
        • 0.551 rounded to the nearest hundredth equals 0.550
  • 6. You do it now!
    • Round to the nearest hundredth
    • 9.718
    • 4.981
    • 0.9876
    • 0.653
