I need help with decimals 2.1 x 5.01?
A simple trick with multiplying decimal numbers is to remove the decimals, multiply the two numbers, then add the decimals back in. The number of decimals you add back in is the total number of decimal places. For example, the stated problem has 1 decimal places in 2.1 and 2 decimal places in 5.01. So first we do the following: 21x501=10521 Now we add 1+2=3 decimal places into the result above: 10.521 That's the answer.
Where do you put the decimal in the answer when you are multiplying decimals?
Lets say that u r doing the problem. 5.2 x 2.1 there are altogether 2 numbers to the right of the decimal, so you take out the decimals, multiply, and add the decimal 2 numbers to the left.
Why are 0.2 and 0.20 not equivalent?
They are, but sometimes a teacher/ program is looking for a specific decimal place to round too, or there can be a significant figure where another number in the problem can have two decimal places requiring two decimals in the answer meaning 0.20 can be a better answer than 0.2
How do you solve a problem with mixed numbers?
I think it's easiest to convert it to a decimal. For example 1 and 1/2 is 1.5. Then, use 1.5 in your calculations since it's easy to solve with decimals
How do you divide decimals by decimals with remainders?
Multiply the division problem by 1, in the form of 10/10, 100/100, 1000/1000,etc. in order to get rid of the decimal divisor. The quotient will still remain the same, as will the remainder. For example, 2.4/.03 is the same as 240/3 = 80. (multiply the original problem by 100/100) 3.5/.2 is the same as 35/2 = 17, remainder 1. (multiply the orig. problem by 10/10)

Can each of the digits 01234 and 5 exactly once to write a decimal subtraction problem The difference must be the same as one of the decimals in the problem?
3.04 - 1.52 = 1.52
Luis starts to do a division problem and notices that there is a pattern in the digits to the right of the decimal point?
The pattern could be that of recurring decimals.
How do you subtract sig figs?
When subtracting (or adding), the answer should have the lowest number if decimals of any number in the problem. For example, 25.1 + 55.89 + 23.321 should equal 104.3 because 25.1 has only one decimal point.
When multiplying decimals do you line them up?
Yes you do that is very important when doing a decimal problem.* * * * *It is important for other basic binary operations but NOTmultiplication.
How do you convert decimals into decimals?
Writing A Fraction As A Decimal-- Divide the numerator by the denominator. Example-two fifths. Divide 5 into 2. You will notice that you cant divide it, so you add a decimal and a zero to the number inside. If you do it right, You should've gotten 0.4 as your decimal you are suppose to divide the denominator by the numerator
How can you use the digits 0 1 2 3 4 and 5 exactly once in a decimal subtraction problem and the difference must be the same as one of the decimals in the problem?
43.0-21.5=21.5

How do you multipy decimals?
Put the number one above another like you are doing a multiplication problem without decimals. Don't try to line the numbers up by the decimals. Multiply like you would normally. When you have your multiplication answer, then you count the number of decimal places in the original and put a decimal point that many in from the end of the answer. 1.2 x .27 -------- 84 +240 ------- 324 Notice that I've ignored the decimal places so far. The next step is to count them in the original numbers. There's one decimal place in 1.2 and two in .27 so there is a total of three decimal places in the original numbers, so I take my answer and put the decimal point 3 spaces in from the right 324 --> .324 , so .324 would be the answer to this example.
