yes, for an example: 4.77 + 3.8 line up the decimals and add zeros so there are the same amount of numbers
4.77+ 3.8 and add a zero so its like this 4.77+3.80 and add

How do you multiply a mixed decimals?
Multiplying mixed decimals is almost just like multiplying whole numbers.For example:5.21 * 1.1You multiply these two numbers as if they didn't have decimal points, and you get 5,731; however, don't forget that you have decimals!Count the total number of digits after the decimal in each factor. You should get 3 since 5.21 has two digits after the decimal, and 1.1 has one digit after the decimal. 2 + 1 = 3Since you have 3 for that total, take the product (which is 5,731) and move the decimal point of that 3 spaces to the left.Your final product is 5.731:]
Which is larger 0.125 or 0.25?
0.25 is larger than 0.125 because it has the larger digit in the tenths place. You can easily compare decimals with different numbers of digits by putting zeroes to the right of the decimal with less digits until they match. For example, 0.25 is the same as 0.250. It should be pretty obvious which is bigger between 0.250 and 0.125.
How many 3 digit numbers can be written with the digits 01357 if repetition is permitted and the numbers should be multiples of five?

When multiplying or dividing two numbers how many significant figures should there be in the answer?
The basic idea is that the final result should not be - or rather, appear to be - more accurate than the original numbers. Therefore, the final result should not have more significant digits than the original numbers you multiply or divide. For example, if one factor has 3 significant digits, and the other 5, round the final result to 3 significant digits.
How can i know the number of decimal places that should be in the product when you multiply two decimals numbers together?
If two numbers, P and Q, have x and y digits after the decimal point respectively, then P*Q has (x+y) digits after the decimal point.
When adding or subtracting decimals how many digits should the answer contain?
as many as needed to satisfy the accuracy needed.
How many numbers does a debit card have?

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 many numbers of at least tree different digits can be formed from the integers 123456?
Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.
