What do you do when you add or subtract decimals?
Adding and subtracting decimals is easy. When you put the numbers one above the other, line up the decimals vertically and treat as you would any whole number just keep the decimals in line and bring it straight down to your answer.
How is adding and subtracting decimals similar to and different from adding and subtracting whole numbers?
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
How do you subtract decimals?
align the decimals and subtract as you normally would. make sure after subtracting you bring the decimal down. replace empty space with zeros. for example: 1.340 - 1.3250 will look like this 1.340 - 1.3250 another example: 10.39485 - 9.847 will look like this. 10.39485 - 9.84700 <----see how I added zeros. When your done subtracting, you bring the decimal straight down to your answer. 7.584 - 5.483 _________ 2.101 SORRY, WHEN I POSTED IT MOVED ALL THE NUMBERS AND TRIED TO RE-POST TO GET THEM TO ALIGN
How do you write down seven-tenths in decimals?
Expressed as a decimal, 7/10 is equal to 0.7.
What do like decimals mean?
A decimal represents a numerical value, less than one, by tens, hundreds, thousands, etc. For example: 1.25 is the whole number "one" plus 0.25, a value less than one. It is also 1 and 1/4th because 0.25 is 25/100ths, which reduces down to 1/4. Like decimals are when two or more decimals are reduced down they are the same my answer before was wrong. Like decimals have the same amount of numbers after the decimal example 5.21 and 9.62
