5. 9/25/2014 1-3 B Multiply by Powers of 10

6. To multiply a decimal by a power of 10 greater than 1, move the decimal point to the RIGHT the SAME # of places as the # of 0s in the power of 10.

7. Example 1 Find 0.26 × 100 0.26 × 100 = 0.26100 has 2 zeros, so move the decimal point 2 places to the right. = 26Since 26 is a whole number, remove the leading zero and decimal point. 0.26 × 100 = 26

8. Example 2 Find 7.69 × 1,000 7.69 × 1,000 = 7.6901,000 has 3 zeros, so move the decimal point 3 places to the right. Annex zeros as needed. = 7,690Remove the decimal point and add a comma. 7.69 × 1,000 = 7,690

9. Example 3 The Sun is about 93 million miles from Earth. Write this number in standard form. 93 million = 93 × 1,000,000The word million means 1,000,000. = 93.0000001,000,000 has 6 zeros. So, move the decimal point 6 places to the right. Annex zeros as needed. = 93,000,000Add commas. The Sun is 93,000,000 miles from Earth.

10. To multiply a decimal by a power of 10 less than 1 move the decimal point to the LEFT the SAME # of places as there are after the decimal point.

11. Example 4 Find 5.75 × 0.01 5.75 × 0.01 = 05.750.01 has 2 places to the right of the decimal point. So, move the decimal point 2 places to the left. = 0.0575Annex zeros as needed. 5.75 × 0.01 = 0.0575

12. Exit Ticket Find each product. 1)14.75 × 100 2)0.034 × 1,000 3)1.98 × 100,000 4)1.98 × 0.1 5)The estimated population of Miami County in 2007 was about 2.4 million. Write this number in standard form. 1,475 34 198,000 2,400,000.198
