Now we are ready to subtract a mixed number from a whole number. Let's find the value of the expression 
.
To solve this example, the number 5 must be presented as a fraction, and the mixed number 
must be converted into an improper fraction. After converting the mixed number into an improper fraction, we obtain a fraction 
. Now subtract fractions with different denominators:
If you subtract one whole pizza and one half pizza from five whole pizzas, you are left with three whole pizzas and one half pizza:
Example 2. Find the value of the expression 
Let us represent 6 as a fraction 
, and the mixed number 
as an improper fraction. After converting the mixed number to an improper fraction, we obtain a fraction 
. Now subtract fractions with different denominators:
Examples on subtracting fractions from a number or subtracting mixed fractions from a number can again be done in the mind. This process is easy to imagine.
For example, if you need to quickly find the value of the expression 
, it is not necessary to represent the number 2 as a fraction and subtract fractions with different denominators. You can imagine the number 2 as two whole pizzas and then imagine cutting two thirds from one of them (two slices out of three).
That leaves 
of the pizza that was cut off 
of it. Plus one of the pizzas will remain intact. That would make one whole pizza and one-third of a pizza:
If you cover two-thirds of the pizza with your hand in the picture (it's shaded), you'll know right away.
