When you multiply decimals, you just ignore the decimal until the end, then, to find the amount of decimal places in your answer, you add the amount of decimal places in both your factors

-- Multiply 73 by 8 , to get 584 .-- Count the total number of decimal places that you've ignored in both factors. (3)-- Mark off that number of decimal places (3) in the product, to get 0.584 .

You multiply the numbers like you multiply integers. Count how many numbers are after the decimal points in both numbers combined and move the decimal point in front of the answer.

Writing a mixed fraction as a decimal is easy. You will have to multiply both top and bottom by 10.

One way to do this is multiply 8x3=24 so 24 has both as factors. Now multiply it by 10 and you have 240. That is a 3 digit number and sill has 8 and3 as factors.

round down till there is not a decimal. example: 4.4*5.6 round to 4*5= about 20 (lower estimate)

You multiply the numbers like you multiply integers. Count how many numbers are after the decimal points in both numbers combined and move the decimal point in front of the answer.

The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.

to find a low estimate for the product of two decimals, round both factors

When you round both factors in a multiplication problem up, your estimate will be greater than the actual product.

the result would be greater than both or more factors, except for when you multiply by 0, 1 or fractions.

If you are a beginner and not comfortable doing divisions when either the numerator or particularly the denominator are decimal fractions, then it is useful to multiply them both by the same power of 10 to get rid of the decimal fractions.

Multiply all factors on both sides of the equation by -1. Alternatively you can multiply any term by (-1/-1).
