Answer 2

To solve this arithmetic expression, let's break it down step by step using the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

10,79:6 means dividing 10,79 by 6, which is approximately 1.7983. 10,7-0,54 means subtracting 0,54 from 10,7, which is approximately 10.16. 3,15:7,9 means dividing 3,15 by 7,9, which is approximately 0.3962.

Now we can substitute these values back into the expression:

1.7983 * 10.16 - 0.3962

Multiplying 1.7983 by 10.16 gives us approximately 18.2858.

Now we have:

18.2858 - 0.3962

Subtracting 0.3962 from 18.2858 gives us approximately 17.8896.

Therefore, 10,79:6,410,7-0,543,15:7,9 is approximately equal to 17.8896.
