Ordering Decimals: 15, 14. 95, 15. 8, 15. 01 First, line up the decimal

Ordering Decimals: 15, 14. 95, 15. 8, 15. 01 First, line up the decimal points 15. 00 14. 95 15. 80 15. 01 Second, add zeroes if needed. Finally, compare the decimals. Always start from the left!! Answer: 14. 95, 15. 01, 15. 8

EQUIVALENT DECIMALS Decimals that name the same number are called equivalent decimals. 0. 60

EQUIVALENT DECIMALS Decimals that name the same number are called equivalent decimals. 0. 60 and 0. 6 Are these the same? ? ?

EXAMPLES: Order these numbers from greatest to least 35. 06, 35. 7, 35. 5,

EXAMPLES: Order these numbers from greatest to least 35. 06, 35. 7, 35. 5, 35. 849 Order these numbers from least to greatest 0. 018, 0. 013, 0. 28, 0. 205, 0. 035

Step 1: Underline decimal place we are rounding Step 2: Circle the number to

Step 1: Underline decimal place we are rounding Step 2: Circle the number to the right of the underlined decimal place Step 3: If circled digit is greater than or equal to 5, then round the underlined number up (add one) Step 4: If circled digit is less than or equal to 4, leave the underlined number the same

Try these: 1)Round 1. 05 to the nearest tenth 2) Round 0. 123 to

Try these: 1)Round 1. 05 to the nearest tenth 2) Round 0. 123 to the nearest tenth 3. Round 4. 568 to the nearest whole number
