Subtracting a whole number from a mixed number (or mixed fraction) involves a few steps.
Here is a step-by-step guide:
Step-by-Step Process
Convert the Mixed Number to an Improper Fraction:
A mixed number has a whole part and a fractional part.
Convert it to an improper fraction.
For example, ( 3 whole 1/4}) can be converted as follows:
Multiply the whole number (3) by the denominator (4): ( 3 times 4 = 12 ).
Add the numerator (1): ( 12 + 1 = 13 ).
The improper fraction is (13/4).
Convert the Whole Number to a Fraction:
Express the whole number as a fraction with the same denominator as the mixed number's fractional part.
For example, to subtract 2 from ( 3 whole 1/4 ):
Convert 2 to ( 8/4} ).
Perform the Subtraction:Subtract the fraction representing the whole number from the improper fraction.
Continuing the example:
( 13/4 - 8/4)
= (13 - 8}/4
= 5/4
Convert Back to a Mixed Number (if needed):
If the result is an improper fraction, convert it back to a mixed number.
For ( 5/4):Divide 5 by 4, which gives 1 with a remainder of 1.
The mixed number is ( 1 whole 1/4).
