To subtract a mixed number from a whole number, first you must make them both fractions. For example, if the problem is 12 and one half - 5, you would multiply 12 by 2, getting 24, and add one, making 25 over 2. Then, just put 5 over one. Now, you must have the 2 bottom numbers be the same, so you have to find the common denominator. The common denominator would be 2, so you leave 25 over 2 the same and change 5 over one to have a denominator of two. To do this, multiply one by two to get 2, and do the same to 5 to get 10. Now you have 25 over 2 - 10 over 2. Subtract the two top numbers to get 15 over 2. To make this a mixed number, divide 15 by 2 to get 7.5, which in mixed number form is 7&1/2.

How to subtract a mixed number from a whole number?
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.
What is a subtracting mixed number?
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.
How can you subtract mixed numbers when the fraction in the first mix number is less than the fraction in the second mixed number?
Yes, you can but you need to "rename" the whole part of the first mixed number.
How do you convert a whole number to a 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.
What does it mean to divide a fraction by a whole number?
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.
