When Dividing a number by a decimal we...

• We make the Divisor into a whole number by moving the decimal point to the RIGHT and the decimal to the RIGHT on the inner number.

• Get rid of the decimal by erasing it

• We make the Divisor into a whole number by moving the decimal point to the LEFT and the decimal to the LEFT on the inner number.

• Add zeros to the inner number
