how do you subtract a fraction from whole number?
11690
When subtracting fractions from whole numbers, you need to change the whole number into a fraction. You then need to make a common denominator and then you can subtract the two numerators and you're all set.

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.

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.

Subtract numbers in a cell 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.

Here's the easy way to subtract fractions that have different denominators: Cross-multiply the two fractions and subtract the second number from the first to get the numerator of the answer. After you cross-multiply, be sure to subtract in the correct order.

Subtracting mixed fractions with unlike denominators? You could first find a common denominator and use it to rewrite each fraction. Then, subtract the whole numbers and fractions separately.

To do this, you need to find the least common multiple (LCM) of the two denominators. To subtract fractions with unlike denominators, rename the fractions with a common denominator. Then subtract and simplify.

To do this, give the whole number a denominator of 1. Convert to fractions of like denominators. The original fraction's denominator is also the least common denominator (LCD) of the two fractions. Multiply the top and bottom of the "whole number fraction" by this number so the fractions have the same denominator.

If your calculator does not have a percent key and you want to add a percentage to a number multiply that number by 1 plus the percentage fraction. For example 25000+9% = 25000 x 1.09 = 27250. To subtract 9 percent multiply the number by 1 minus the percentage fraction. Example: 25000 - 9% = 25000 x 0.91 = 22750.

Write both fractions as equivalent fractions with a denominator of 15. Since you're trying to subtract a larger fraction from a smaller one, you need to "borrow" a one from the integer 4, change it to 15/15, and add it to the fraction. Now the problem becomes 3 20/15 minus 3 9/15 and the answer is 11/15.
