how do you subtract fractions with whole numbers?
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.

To square a fraction, you multiply the fraction by itself. Another way to think about it is to multiply the numerator by itself and then the denominator by itself. For example: (5/2)2 = 5/2 × 5/2 or (52/22).

Step 1: Separate the whole number from the fractions. Step 2: Now we will add the whole numbers together and add the fractions together. To add the fractions we need common denominators. Now that we have common denominators, we can add the numerators and leave the denominator the same.

Divide the percentage by 100 to get a decimal number. Use that number as the numerator (top) of a fraction. Put a 1 in the denominator (bottom) of the fraction. Convert the decimal to a whole number: Count how many places are to the right of the decimal.

Subtracting Whole Numbers, with Regrouping When you regroup, you rewrite the number so you can subtract a greater digit from a lesser one. When you're subtracting, just regroup to the next greater place-value position in the minuend and add 10 to the digit you're working with.

To subtract fractions with unlike denominators, rename the fractions with a common denominator. Then subtract and simplify. The LCM of 3 and 11 is 33 .

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.
