**Step 1 (supplementary calculation): Addthe two fractions**

As a first step only add the two fractions in a supplementary calculation. We deal with the whole-number parts later in the second step:

**Step 1.1: Determine the common denominator:**

Nothing to do. The denominators are the same!

**Step 1.2: Expand to the common denominator:**

Nothing to do. The denominators are the same!

**Step 1.3: Add the numerators:**

Since the two fractions have a common denominator, you can add:

3 | + | 1 | = | 3 + 1 | = | 4 |

5 | 5 | 5 | 5 |

**Step 1.4: Check whether the result can be simplified**

The result can not be simplified.

**Step 1.5: Convert into a mixed number**

The numerator is lower than the denominator - it's a **proper fraction** that cannot be converted to a mixed number.

**Step 2: Calculate the result**

**Step 2.1: fraction part of the result**

The fraction part was calculated in step 1. It can be transferred directly to the result:

1 | 3 | + | 2 | 1 | = ? | 4 |

5 | 5 | 5 |

**Step 2.2: whole number part of the result**

The whole numer part of the result is the sum of the original whole numbers:

1 + 2 = 3

The result is:

1 | 3 | + | 2 | 1 | = 3 | 4 |

5 | 5 | 5 |
