Answer 2

To solve the expression you've provided, let's break it down step by step:

7,5:3 represents division. So, we start by dividing 7.5 by 3:

7.5 ÷ 3 = 2.5

Next, we have the expression 9/11 - (11/49 * 21/22 + 3.75). Let's simplify this part:

Starting with the parentheses:

11/49 * 21/22 = (11 * 21) / (49 * 22) = 231 / 1078

Now, let's add 3.75 to the result:

231 / 1078 + 3.75 = (231 + 3.75 * 1078) / 1078 = (231 + 4032.5) / 1078 = 4263.5 / 1078

Finally, subtract 9/11 from the previous result:

4263.5 / 1078 - 9/11 = (4263.5 * 11 - 9 * 1078) / (1078 * 11) = (46898.5 - 9702) / 11858

Now we can calculate the final result:

(46898.5 - 9702) / 11858 ≈ 3.392

Therefore, the value of the expression 7,5:3 9/11-(11/49*21/22+3,75) is approximately 3.392.
