When adding and subtracting decimal numbers, what should you do after lining up the decimal points?

• Fill in any empty spaces with zeros

• Slide the decimal points to the right so that the numbers become whole numbers

When multiplying decimals, the total amount of numbers to the right of decimal points in the problem will..

• be the same as in the answer

• be more than the amount in the answer

If you have a decimal divisor and a whole number dividend, what will you need to do to the dividend as you begin to solve?
