What is simplest form?

A fraction is in its simplest form when the numerator and denominator have no common factors other than 1. This means the fraction cannot be reduced further by dividing both the numerator and denominator by a common number.

For example, 2/4 is not in simplest form because both 2 and 4 can be divided by 2, resulting in 1/2. The fraction 3/5 is already in simplest form because 3 and 5 have no common factors other than 1.

How to simplify fractions

To simplify a fraction, follow these steps:

1. Find the greatest common divisor (GCD) of the numerator and denominator.
2. Divide both the numerator and denominator by the GCD.
3. The resulting fraction is in simplest form.

The GCD is the largest number that divides both the numerator and denominator without leaving a remainder. You can find the GCD by listing all the factors of each number and identifying the largest common one.

Example calculation

Let's simplify the fraction 10/15 step by step.

1. Find the factors of 10: 1, 2, 5, 10
2. Find the factors of 15: 1, 3, 5, 15
3. The common factors are 1 and 5. The greatest common divisor is 5.
4. Divide both numerator and denominator by 5: 10 ÷ 5 = 2, 15 ÷ 5 = 3
5. The simplified fraction is 2/3.

Common mistakes

When simplifying fractions, it's easy to make a few common errors:

• Choosing the smallest common factor instead of the greatest common divisor. For example, using 1 instead of 5 for 10/15.
• Forgetting to divide both the numerator and denominator by the same number.
• Not checking if the fraction can be simplified further after the first division.
