**So, in order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.**

- Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.
- Step 2: Make sure all radicals are simplified.
- Step 3: Simplify the fraction if needed.

Accordingly, how do you cross multiply to find X?

**Method 1**

**Cross Multiplying with a Single Variable**

- Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction.
- Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction.
- Set the two products equal to each other.
- Solve for the variable.

How do you isolate the variable?

Put every term that contains the

**variable**on one side of the equation and every term that does not contain a**variable**on the other side. Divide both sides of the equation by the coefficient – the number attached to the**variable**. Solve for x. The solution is x = 4.How do you solve a fraction?

**Method 3**

**Converting Mixed Numbers into Improper Fractions**

- Convert mixed numbers into improper fractions.
- Take the whole (non-fraction) number and multiply it by the denominator.
- Add that answer to the numerator.
- Put that amount over the original denominator and you will have an improper fraction.
