To do simple subtraction, use the - (minus sign) arithmetic operator. For example, if you enter the formula =10-5 into a cell, the cell will display 5 as the result.

To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form. To subtract 20 percent, multiply by 80 percent (0.8).

Subtraction of Algebraic Fractions. To subtract algebraic fractions, first express them in terms of their Lowest Common Denominator (LCD) and then subtract their numerators to obtain the numerator that is divided by the LCD to arrive at the answer.

Remember, you can only add and subtract fractions when the bottom numbers, or denominators, are the same. So, to add or subtract fractions: Change the fractions so they have the same denominator. Add or subtract the top numbers, or numerators.

Note: The rules for adding and subtracting improper fractions are the same as working with proper fractions. Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. Step 3: If the answer is an improper form, reduce the fraction into a mixed number.

Subtracting mixed fractions? You could first convert each to an improper fraction. If they don't have common denominators, then find a common denominator and use it to rewrite each fraction. Then, subtract the fractions and simplify.
