Example Questions
Example Question #3 : How To Subtract Fractions
Evaluate:
By order of operations, subtractions are carried out in left-to-right order, so subtract 4.70 (adding the placeholder zero) from 7.82, aligning the decimal points:
Now subtract 2.56 from this difference, again aligning vertically by decimal point:
Example Question #4 : How To Subtract Fractions
Evaluate:
Rewrite this difference as a sum. The sum of two numbers of unlike sign is the difference of their absolute values, with the sign of the "dominant" number (the negative number here) affixed:
Subtract vertically by aligning the decimal points, making sure you append the 9 with a decimal point and two placeholder zeroes:
Since the answer is negative, append a negative symbol in front. The answer is 
Example Question #451 : Concepts
Subtract:
Since you are subtracting a larger number from a smaller, reverse them, and affix a negative symbol:
Rewrite vertically, lining up the decimal digits. Subtract as you would two integers. (Note that you are appending a zero to the 0.15.)
Affix the negative symbol to obtain the difference of 
Example Question #452 : Concepts
Evaluate:
Subtract the first two fractions first. This is best done by writing vertically, and subtracting integer and fraction parts.
Now add this to the third fraction similarly, adjusting as shown for the improper fraction:
Example Question #453 : Concepts
Subtract:
Subtract vertically, making sure the decimal points in all three numbers line up (note that a zero has been appended to the first number):
Example Question #8 : How To Subtract Fractions
Subtract:
Rewrite the first fraction in eighths, as 
Now write vertically:
"Borrow" in the first expression, then subtract integer and fractional parts separately:
Example Question #454 : Concepts
Subtract the numerators:
Answer:
Example Question #1052 : Hspt Mathematics
Which of the following expressions is equal to 
Rewrite 
Now subtract:
Example Question #11 : How To Subtract Fractions
Which of the following is equal to 
Subtract vertically, making sure the decimal points line up.
This is twelve tenths; write this as a fraction and simplify:
Example Question #12 : How To Subtract Fractions
In order to subtract fractions we need to have a common denominator (the number on the bottom of each fractions). In this case we do have common denominators.
We need to then subtract the numerators, in this case 
After subtracting the numerators we keep the denonimator the same.
This is known as an improper fraction because the numerator is greater than the denominator. So we need to rewrite into a mixed number. Fractions can also be read as division, meaning 4 divided by 3 is????
