Dividing Decimals by the Power of Ten/Exponents

1. Notes

1.1. Dividing decimal numbers by the Power of Ten

1.2. Students will undestand that when dividing a decimal by a Power of Ten that the number will decrease by a unit of 10.

1.3. If a decimal number is divided by a power of 10, the digits in the dividend remains unchanged but the decimal point is moved to the left by a number of places equal to the number of trailing zeros in the power of 10.
