6 * 0.9 + 0.1 : 4-0.23

5.195

Step-by-step explanation:

To solve the different operations of a mathematical expression there are rules that must always be followed, that is, there is a hierarchy of operations that must be respected.

The hierarchy of operations works as follows:

First, operations in brackets, brackets or braces are resolved independently.

Next, the powers and roots are realized.

It continues to solve multiplications and divisions.

Finally, the addition and subtraction are carried out, regardless of the order.

6 x 0.9 + 0.1 / 4 - 0.23 =

First, multiplications and divisions:

5.4 + 0.025 - 0.23.

Then, addition and subraction:
