Make it into an both numbers an improper fraction and then do the opperation.
just change the fration with the smallest denominator and add or subtract the way you always do.
you take away one of the whole number=then you add or subtract your fractions=
they must have a common denominator
Convert them to improper fractions with common denominators and proceed.
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...

When subtracting mixed numbers one of the fractions may need to be renamed.
Find theLeast Common Denominator (LCD)Find the equivalent fractions.Add or subtract the fractions and add or subtract the whole numbers.Write your answer in lowest terms.
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.

First you would want to change the mixed number to an improper fraction. Then you can subtract
You need to understand that a mixed number such as 5 1/3 really means 5 plus 1/3. You can do your calculations accordingly. To add and subtract, you can add and subtract the whole part and the fractional part separately. To multiply or divide, you can convert the numbers to improper fractions first - though in some cases it is easier to use the distributive property.
I believe there is only one difference. The mixed numbers have to be converted to fractions. After that the operation is the same. Each fraction then must have a common denominator in order to add or subtract which is true in either case. Perhaps you need to convert back to mixed number however you might have to do that also when adding fractions. Example 9/16 +9/16 =18/16 = 1 1/4. And in subtracting mixed numbers you might end up with a complete fraction thus not needing conversion. Therefore I see only one definite difference as described above on the first paragraph.
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
To combine the fractions or subtract the fractions. Same method with mixed numbers.
SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.
when people subtract and when there done turn it in to a mixed number.
Make them into improper fractions, find the least common denominator, convert them, subtract, reduce if possible.
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
