WRITING DECIMALS THREE FORMS: Standard: 2015. 05 Expanded: 2000 + 10 + 5 +

WRITING DECIMALS THREE FORMS: Standard: 2015. 05 Expanded: 2000 + 10 + 5 + 0. 05 Word: two thousand fifteen and five hundredths If you can say it, you can write it!! Tips for writing in expanded form Write the number that appears before the decimal point in expanded form. For decimals, place a zero in the ones place. Also, substitute zeroes for all spaces after the decimal point that come before the digit that you are working with.

PRACTICE Standard form 0. 085 Expanded form Word form 90000 + 800 + 10

PRACTICE Standard form 0. 085 Expanded form Word form 90000 + 800 + 10 + 3 + 0. 07 + 0. 006 + 0. 0005 Ten and forty one hundredths 400 + 50 + 2 + 0. 7 + 0. 09 + 0. 002 86, 945. 56 Four thousand nine hundred ninety one and six tenths

COMPARING DECIMALS If you are comparing tenths to hundredths, you can use a tenths

COMPARING DECIMALS If you are comparing tenths to hundredths, you can use a tenths grid and a hundredths grid. Here, you can see that 0. 4 is greater than 0. 36.

Comparing Deicmals Example: 12. 36 ___ 12. 24 Step 1: 12. 36 12. 24

Comparing Deicmals Example: 12. 36 ___ 12. 24 Step 1: 12. 36 12. 24 Step 2: no zeros needed Step 3: the same digits are in the tens and ones place In the tenths place 3 is bigger than 2. So 12. 36 is greater than 12. 24 Answer: 12. 36 >12. 24
