You can do this by temporarily ignoring the fraction part of the mixed number as long as you put it back again when finished!
For example,
For 3 1/4 - 2:
Here we can simply do 3 - 2 which is 1, and then add the fraction back again = 1 + 1/4 = 1 1/4

You convert the mixed numeral into an improper fraction. Now subtract the improper fraction from the whole number by putting the whole number over 1.
Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.
Yes, you can but you need to "rename" the whole part of the first mixed number.
A whole number could be converted to a mixed number, but that might only be useful when subtracting a mixed number from a whole number. To change a whole number to a mixed number, simply take one away from the whole number and then change the 1 to a fraction that is equivalent to 1 (numerator and denominator are the same). For example 5 - 2 1/4. To subtract, you might want to change the 5 to 4 4/4. Then, you can subtract 1/4 from 4/4 to get 3/4 and 2 from 4 to get 2. The answer is 2 3/4.
It means how many times you can subtract the whole number from the fraction before you reach zero. Assuming you've not got a mixed fraction, the whole number will only be able to be subtracted a fractional number of times.
