To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example:
5.12 x 6.35 = 32.5120.
If the numbers were 51.2 x 63.5, the answer would be 3251.20.
It's because decimals are really fractions and all numbers get smaller when you multiply them by fractions.
Pretend there are no decimal points, and multiply the numbers together. Then count over (from the right) the number of decimal points of the two numbers combined. For example: 3.4 * 0.185 = 0.6290 34 * 185 = 6290. There is one number to the right of the decimal point in 3.4, and three to the right in 0.185. One plus three is four, so starting from 6290. you move over four places.
whenever you multiply a whole number by a decimal you get a decimal. 2.9x100=290
write the following decimal numbers in words .0087945
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.
line up the numbers and decimals multiply regularly then bring the decimal down
The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.
Example of multiplying whole decimal numbers: 2.37 × 3.56 = 8.4372 Remove the decimal point and multiply as for whole numbers: 237 × 356 = 84372 Then add the decimal point, thus : 8.4372
Often, yes. But it depends on the numbers. For example, if you multiply 1.5 x 2, you get 3 as the answer (whole number). But if you multiply 1.5 x 3, you get a decimal of 4.5
the product will have four decimal places
The same way you multiply any other decimal numbers. The result is 10,042.95.
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
arrange and multiply the number like whole numbers. count the number of decimal places. start from the rightmost, put the decimal point based on the total number of decimal places
Add, subtract, multiply and divide.
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.
