#### What is 28/40 in simplest form?

**Final Answer:**

The fraction can be simplified by finding the greatest common factor, which is 4. Dividing both the numerator and denominator by 4 gives us . Therefore, in simplest form is .

**Examples & Evidence:**

To simplify the fraction , we need to find the greatest common factor (GCF) of the numerator (28) and the denominator (40).

1. First, let’s find the factors of 28:

- The factors are: 1, 2, 4, 7, 14, and 28.

2. Now, let’s find the factors of 40:

- The factors are: 1, 2, 4, 5, 8, 10, 20, and 40.

3. The common factors of 28 and 40 are: 1, 2, and 4.

- The greatest common factor is 4.

Now, we can divide both the numerator and the denominator by their GCF (4):

Thus, the simplified form of is .

**Explanation:**

An example of simplifying another fraction is . The GCF is 5, so when you divide both by 5, you get . This demonstrates the same process used for simplifying .

The method of simplifying fractions by finding the GCF is a standard mathematical practice, which can be found in basic arithmetic textbooks and resources. This process ensures that fractions are expressed in their simplest form, making calculations easier.
