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