Stack the numbers larger number on top.

Align the decimal points.

If a number has fewer decimal places extend it with zeros

Subtract the top bottom number from the top number from right to left.

Borrow and reduce as needed to solve the problem.

Check your work make sure your decimals line up

Start by stacking your numbers largest number on top.

You do not need to align the decimal points in multiplication

Follow standard multiplication steps

Multiply the ones place with the top number

multiply the tens place to the top number

Remember for every place value on the bottom number you should have a new row to add together

Also use zero as spacers when starting the new row Example the third row should have 2 zeros since it represents the 100's place

When you have multiplied all of the bottom digits against the top number add the products.

count how many decimal places were in the original numbers and from the right count to the left and place the new decimal point.

Set up your division problem for long division

Ignore the decimal places for now

going from left to right divide the dividend by the divisor and solve to get the quotient

Count how many decimal places were in the original problem

counting from right to left place the decimal point to the left of the number of places in your quotient
