What do you do with the decimal point when multiplying?

When you multiply decimals first you should take away the decimals and just leave the number. Then multiply the two numbers together and you get a larger number than the two numbers you have. Then you have to count out how many decimals places you orignally had in both of the numbers then you put how every many decimal place in the first two numbers in the answer. Let me show you an example 34.56 x 76.096 Take away the decimals 3456 x 76096 Find the answer to this 262987776 Now go back to your two original numbers and find how many decimals places they each have 34.56 has 2 decimals 76.096 has 3 decimals Since you have 2 and 3 decimals you have to put 5 decimal places in your final answer 2629.87776 this is your answer


How do you multiply two-digit numbers in a decimal?

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.

How is multiplying two decimals similar from multiplying one decimal by a whole number?

You simply multiply the two numbers together ignoring the decimal point. You then count the number of decimal places in each of the multiplicands and add them together. In the product, you put the decimal point so that there as many digits after the decimal point as that sum.For example, to multiply 2.63 by 3.271263 * 3271 = 860273.There are 2 digits after the decimal point in the first multiplicand and 3 in the second. 2 + 3 = 5So the decimal point in the answer is placed so that there are 5 digit after it: 8.60273
