Example Question #171 : Decimals
To subtract decimals you place the first decimal over the top of the other aligned by the decimal point. If there are no numbers after a tens, hundredths, or thousandths place or further to the right of the decimal just add a zero in the required areas.
For example 
Then go through each place and subtract the top number by the bottom number. Subtract the numbers in each place like you would any number.
The example we are working with will look like this
The answer after subtraction is
Example Question #273 : Concepts
Subtract:
Rewrite the decimal as a fraction and subtract:
Reduce this:
Example Question #172 : Decimals
Evaluate:
Add the first two numbers, making sure you align the decimal points in the addends and the sum:
Now subtract the third number, making sure you again align the decimal points:
Example Question #275 : Concepts
Combine:
First, combine the positive decimals, which gives you 
Then, you can subtract that from 
Your answer is 
Example Question #4 : How To Find The Decimal Equivalent Of A Fraction
Write the value of this expression as a decimal:
Simplify the sum by taking the least common denominator, which is 12:
Divide 13 by 12:
Example Question #1 : Other Decimals
Simplify the following:
To add decimals, first add zeros to the necessary terms so they all have the same number of places to the right of the decimal point.
Now, temporarily drop the decimal and add the numbers as if they were whole numbers.
Finally, add the decimal place back in, in the same place you removed it from. In this case, we originally modified our numbers so they all had 3 numbers to the right of the decimal, so we will add the decimal back to the exact same place. Thus, our answer is:
Example Question #173 : Decimals
Add:
Rewrite the problem so that the tenths, hundredths, and thousandths digits align. Use zeros as placeholders and solve.
Example Question #174 : Decimals
Which of the following is the sum of nine tenths and nineteen thousandths?
The correct response is not given in the other choices.
Nine tenths is equal to 0.9; nineteen thousandths is equal to 0.019. Add them, rewriting 0.9 as 0.900:
Example Question #176 : Decimals
Add:
Ensure that each digit is added to the correct digit.
Add three zeros at the end of 
Add the tenths place with the tenths place (in this case 
Example Question #282 : Concepts
Add
Add the placeholder for the hundredths place after 
Rewrite the problem:
Add the hundredths place.
Add the tenths place.
Combine the numbers.
The decimal place is two places from the right.
The correct answer is:
