Question

7 1/3 : (7/9-9/5)-2*1 1/4 Даю 40 баллов!

Answer 1

Ну как то так. вроде правильно.

Answer 2

Thank you for offering 40 points! However, it seems like you have provided a mathematical expression that needs to be solved. Let's solve it step by step:

1. Convert the mixed numbers to improper fractions: 7 1/3 = (3 * 7 + 1) / 3 = 22 / 3 2 1/4 = (4 * 2 + 1) / 4 = 9 / 4

2. Perform the operations inside the parentheses first: (7/9 - 9/5) = (35/45 - 81/45) = -46/45

3. Now, rewrite the expression with the results from step 1 and step 2: 22 / 3 - (-46/45) - 2 * 9/4

4. Perform the operations from left to right: 22 / 3 + 46/45 - 18/4

5. Find a common denominator (lowest common multiple of 3, 45, and 4), which is 180: (22 * 60 + 46 * 4 - 180 * 9) / 180 (1320 + 184 - 1620) / 180 (-116) / 180

6. Reduce the fraction to its simplest form (divide numerator and denominator by their greatest common divisor): (-29) / 45

So, the final result is -29/45.
