It seems like you're providing a mathematical expression for evaluation. Let's break it down step by step:

1. 0,09 + 3,61: This is a simple addition operation. Result: 0.09 + 3.61 = 3.70

2. 3,70 : 1/5: This is a division operation. Remember that "1/5" is the same as 0.2 when expressed as a decimal. Result: 3.70 / 0.2 = 18.50
