To multiply decimal numbers, the decimal point is ignored and the multiplication is done as though they were (large) integers.
The last step is to put the decimal point into the answer by ensuring the same number of digits follow it as were following the decimal points in the numbers multiplied together; trailing zeros can be removed at this point.

What are the 3 steps to multiplying decimals?
STEP 1:Take out the points and multiply as normal. STEP 2:After multiplying,count the numbers that are after the decimal points. STEP 3:Then look at your answer and put in your decimal places from the right to the left.
How do you multiply a decimal by a whole number?
This is my way of doing it:The first step is, you basically multiply like normal vertically. So for example, say you want to multiply 632 x .035 :632x .035---------3160+18960---------22120After you have done that, you simply count haw many numbers there are after each decimal point. In this case there is only one decimal point with 3 numbers after it. Let me first say that when you have a whole number, there will ALWAYS be an invisible decimal point at the end of the last number. With that in mind, you now know that there is an invisible decimal point at the end of 22120 which was the partial answer to the multiplication problem above. So now you add the decimal point and the zero to then end of your number(it's ok to have a zero at the end because that indicates nothing, you don't have to, but the point is necessary):22120.0 When you have this done, you will move the decimal point to the left however many spaces that equals how many numbers you had after the decimal point in total from the original numbers. So, above we said that there was three numbers after the decimal point in the number 0.035, so now you move the decimal point three spaces to the left in your multiplication answer:22120.0 ------> 22.1200 From here you can get rid of all the zeros after the decimal point, for they are not necessary in this step:22.12 That's the answer, and that is how you multiply a whole number x a decimal number.Hope I helped
What are three fractions that are equivalent to 0.60?
1. Write this as 60/100. 2. Simplify the fraction as much as you can. 3. In the result of step (2), multiply top and bottom by the same number, to get an additional fractions. You can repeat (with the result of step (2)), multiplying top and bottom with different numbers (but always the same number for top and bottom), to get additional equivalent fractions.
What is 7.3125 in a fraction in simplest form?
To convert a decimal to a fraction, you start by multiplying that decimal by a power of 10 such that there are no digits after the decimal point. In this case you can multiply by 10,000 to get 73,125. Put this power of 10 as the denominator and we have a starting point of 73125/10000. The next step is to identify any common factors between the denominator and the numerator. In this case, both top and bottom can divide by 625, and doing this gives 117/16. This fraction is in its simplest form, and thus 7.3125 as a fraction is 117/16.
What is the mean of 834 1099 775 900 970?
Formula: Step 1) 834 + 1099 +775 + 900 + 970 = 4578 Add up all the numbers, and get the total Step 2) 4578 / 5 = 915.6 Take the answer and divide it by how ever many numbers you added up in step 1 In this case there are 5 different numbers. Step 3) 915.6 is the mean.

What is the last step when multiplying binomials?
Combining like terms.
What are the multiplication rules for binary?
It is very simple by multiplying binary numbers. Following are the procedure for multiplying binary numbers. Step 1: When we multiplying 0 and 0, we get 0. 0 x 0 = 0 Step 2: When multiplying 1 and 0, we get 0 1 x 0 = 0 Step 3: When multiplying 0 and 1, we get 0 0 x 1 = 0 Step 4: When Multiplying 1 and 1, we get 1 1 x 1 = 1
How do you divide 112 by 8.40?
Move the decimal in both numbers 1 spot to the right. 112 becomes 1120 and 8.40 becomes 84 Then, you can divide 1120 by 84 is 13.333 (repeating decimal) The reason you can do the first step is because you are multiplying both the numerator and the denominator by 10, which is the same as multiplying them by one.
Can you compare multiplying integers with multiplying decimals?
Yes, you can. The method used - column multiplication - is exactly the same in both cases; you simply have the additional step of locating the decimal point.
What are the steps to multiplying rational numbers?
Step 1 Make the whole number a fraction by making it ?/1 Step 2 Make the mixed number a improper fraction by multiplying the denominator by the whole number and then adding the numerator and putting that on top of the original denominator. Step 3 SOLVE using basic multiplying fractions rules Step 4 SIMPLIFY
What are step in adding decimals?
Write the numbers in a column so that all the decimal points are one below the other. Put a decimal point in the answers underneath the coumn of decimal points. Then add the numbers ignoring the decimal points.
How you use the algorithm when multiplying fractions by fractions?
step by step
How do you convert a number in to a fraction?
I assume you mean a decimal number. Move the point to the right, counting the steps until at last you have no more numbers to the right, or only zeros. Each step is equivalent to multiplying by 10. Suppose there are N steps. The number you now have on the left, divided by 1 followed by N zeros is your fraction. So 1.234 becomes (with 3 steps) 1234/1000
What is the first step when you add rational numbers with decimals?
You write them, one below the other, with their decimal points aligned.
How does the Russian peasent algorithum work?
Russian Peasant Multiplication is a multiple-step replacement for multiplying large numbers. See the related link for an excellent explanation.
How do you change decimals into fractions in simplest form?
Step 1: Write down the decimal divided by 1, like this: decimal/1 Step 2: Multiply both top and bottom by 10 for every number after the decimal point. For example, if there are two numbers after the decimal point, then use 100, if there are three, then use 1000, etc. Step 3: Simplify ( or reduce) the fraction.
