how do you multiply decimals???? the easiest way?????????

Question

TELL ME FROM STEP 1-STEP WHATEVER AND YOULL RECIEVE TEN POINTS PLUS 5 STARS (ONLY WHO ANSWERS THE BEST) (AND THE EASIEST WAY) !!!!!!!!!!!!!!!!!!!!

Answer 1

I seldom count the number of decimal places. I might count wrongly. There might be many of them to count. Some blur people might see and learn incompletely and count the tailing zeros (e.g. 32.4500).

I look at the value of the numbers being multiplied, and mentally estimate a rough value. Then places the decimal points so that the result is closest to the estimate value.

E.g. 1.25983 * 34.9839571
The product should be about 35, or 40, whatever, doesn't matter much here.
Then, after multiplied ignoring the decimal points:
44073838673293
It is quite obvious that 44.073838673293 is the answer.

Answer 2

7.25
x .5
-------
forget the decimals for now.. just multiply 725 x 5

your answer is 3625

now count how many numbers are behind the decimal in your problem

7.25 has 2 numbers behing the decimal (numbers 2 and 5)

.5 has onlyone number behind the decimal (number 5)

so there are a total of 3 humbers behind the decimal

go back to your answer 3625
now start from the right and move over 3 numbers then put a decimal there

3 6 2 5
_^ ^ ^
_3 2 1
--------
3.625

Answer 3

How do we multiply decimals?
0.2 × 6.03

Ignore the decimal points -- do not align them -- and multiply the numbers as whole numbers. Then, starting from the right of the product, separate as many decimal places as there are in the two numbers together.

Example 1) 0.2 × 6.03

Solution. Ignore the decimal points. Simply multiply

2 × 603 = 1206

Now we must put back the decimal points. Together, .2 and 6.03 have three decimal places. Therefore, starting from the right, separate three places:

1.206

When we ignore a decimal point, we have in effect moved the point to the right:

6.03 → 603

We have multiplied by a power of 10. Therefore, to compensate and name the right answer, we must divide by that power, we must separate the same number of decimal places.

Answer 4

Count the digits on the right side of the decimals for all numbers your multiplying by, then remove the decimals. Replace the decimal starting from the left and count how many you tallied from before

1.23
1.456

Total number 5
123 x 1456 = 179088 move decimal 5 over 1.79088

Answer 5

first multiply the numbers as you normally would and ignore the decimals.

next, starting on the top original number... count the numbers to the right of the decimal

do the same for the bottom number.

Add these two numbers up.

now, go to the answer you originally received and start counting at the last (rightmost) number to the left. Stop when you get to number you just added.

insert the decimal here

for example:

52.3
x 1.26
65.898

Hope this helps.
