I will use "root" as a symbol for square root. I assume you want to get rid of the square root in the denominator; this will usually bring some square root into the numerator.... Negative exponents are a way of writing powers of fractions or decimals without using a fraction or decimal. You use negative exponents as a way to combine expressions with the same base, whether the different factors are in the numerator or denominator.

**Simplifying Square Roots and Rationalizing Denominators**

The numerator, one, is the number you had, and the denominator, two, is the number of pieces total. Tell students: Now letâ€™s practice numerator and denominator. Display Candy Activity Sheet on the overhead projector and show students five different colored Skittles candies....Eighteen is missing one factor of 2 â€”so you multiply the numerator and denominator \(\frac{5}{18}\) by 2 to get an equivalent fraction with denominator 36. We will apply this method as we subtract the fractions in the next example.

## How To Bring A Denominator To The Numerator

### Watch videoÂ Â· When we have a fraction with a root in the denominator, like 1/âˆš2, it's often desirable to manipulate it so the denominator doesn't have roots. To do that, we can multiply both the numerator and the denominator by the same root, that will get rid of the root in the denominator. For example, we can multiply 1/âˆš2 by âˆš2/âˆš2 to get âˆš2/2

- Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the numerator. Since we have a square root in the numerator, then we need to multiply by the square root of an expression that will give us a perfect square under the radical in the numerator.
- a) To compare two fractions of the same sign (both positive or both negative) that have different denominators and numerators (unlike denominators and unlike numerators), fractions should be brought to the same denominator (or if it's easier, to the same numeratorsâ€¦
- Multiply the numerators to get the new numerator and multiply denominators to get the new denominator, like this: Then simplify by reducing the new fraction to lowest terms . To multiply a fraction by a whole number, just multiply the fractionâ€™s numerator by the whole number to get the new numerator, like this:
- Before we can add or subtract fractions, the fractions need to have a common denominator. Iin other words the denominators must be the same. Making The Denominators the Same. To make the denominators the same we can: Multiply top and bottom of each fraction by the denominator of the other. Like in this example (press play button): This always works, but we often need to simplify the â€¦
