Finding a Pattern – Multiplying and Dividing Using Powers of 10 Part B Look for patterns: larger 1. When multiplying by powers of 10, the number gets __________. 3 places 2. If a number is multiplied by 103, the decimal shifts _________ right (number of places) to the ________of its original position. 2 places 3. If a number is divided by 102, the decimal shifts ________ (number left of places) to the ______of its original position.

Summary When multiplying by powers of 10 the number gets larger, so shift the decimal to the right the same number of places as the exponent in the power of 10. Fill in any blanks in front of the decimal with zeros.

Summary When dividing by powers of 10, the number gets smaller, so shift the decimal to the left the same number of places as the exponent in the power of 10. Fill in the blank places behind the decimal with zeros and add a zero to the left of the decimal if there is no other digit to the left of the decimal.
