are the numbers produced when starting with one

• are the numbers produced when, starting with one (1), and repeatedly collect them into groups of 10. • 1, 100 etc • 0. 1, 0. 001 etc

Number Ten (10) • Number Ten (10) is a collection of ten Ones. • 10 = 10 x 1

Number One Hundred (100) • One Hundred (100) is a collection of ten Tens. • 100 = 10 x 10

Number One Thousand (1 000) • One Thousand (1000) is a collection of ten One Hundreds • 10 x 100 •

One Ten One hundred One thousand Ten thousand One hundred thousand One million Ten million One hundred million One billion Ten billion 1 10 100 1, 000 100, 000 1, 000, 000 10, 000, 000 One hundred billion 100, 000, 000

- Add a place for as many zeroes as appear in the power - The decimal moves as many places to the RIGHT as there are zeroes - Remember multiplying a whole number by a whole number means the answer should be bigger! 89 x 10 =89. x 10 = 890. Decimal moves to the right one place

Examples 36 × 10 = 360 Add on one 0. (1 place) 36 x 100 = 3600 Add on two 0's. (2 places) 36 x 1000 = 36 000 Add on three 0's. (3 places)

-Take a place away for each place past the decimal until a whole number is reached e. g. 0. 01 means move 2 places 0. 01 moves 2 places to the right to get 1 ** Remember multiplying a decimal number by a whole number means the answer should be getting smaller!

Examples 3400 x 0. 001 = 3400 = 3. 400 = 3. 4 3400 x 0. 01 = 3400 = 34 3400 x 0. 1 = 3400 = 340 The decimal in the whole number moves as many places to

-Or move the decimal to the LEFT for each zero in the denominator e. g. 0. 01 is equal to 1/100 and there are two zeroes in the denominator 0. 1 = 1/10 1 zero = 1 place to the LEFT 0. 01 = 1/100 2 zeroes = 2 places to the LEFT 0. 001 = 1/1000 3 zeroes = 3 places to the LEFT 0. 0001 = 1/10 000 4 zeroes = 4 places to the LEFT

Examples 3400 x 0. 001 = 3400 x 1/1000= 3. 400 = 3. 4 (3 places) 3400 x 0. 01 = 3400 x 1/100 = 34 (2 places) 3400 x 0. 1 = 3400 x 1/10 = 340. 0 = 340 (1 place) The decimal in the whole number moves as many places to
