how do you subtract whole fractions?
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.

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.

['Leave the first fraction in the equation alone.', 'Turn the division sign into a multiplication sign.', 'Flip the second fraction over (find its reciprocal).', 'Multiply the numerators (top numbers) of the two fractions together. ... ', 'Multiply the denominators (bottom numbers) of the two fractions together.']

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.

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.

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). To subtract 30 percent, multiply the number by 70 percent (0.7).

Subtracting Whole Numbers. To subtract whole numbers we write them as in an addition problem and subtract each digit moving from the right to the left. If when subtracting digits, the top number is smaller than the bottom, borrowing becomes necessary.
