Answer 3

To understand how the equation "10,9:4=109/40" is derived, let's break it down step by step:

Step 1: 10,9 The comma in this context is used as a separator between two numbers. So, "10,9" actually represents the number 10.9.

Step 2: 10.9:4 Here, the colon ":" represents the division operation. So, "10.9:4" means 10.9 divided by 4.

Step 3: 10.9 / 4 = 2.725 When you perform the division of 10.9 by 4, you get the result as approximately 2.725.

Now, the equation becomes: 2.725 = 109/40

Step 4: Simplifying the fraction 109/40 To simplify the fraction, you can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 109 and 40 is 1 (as 109 and 40 are relatively prime numbers).

So, 109/40 cannot be simplified further into an integer or a fraction with smaller numbers.
