Answer 1

Ответ:

Пошаговое объяснение:

(1 4/9 + 2 5/6 - 2 3/4) * (5/11 + 10/20) = (1 16/36 + 2 30/36 - 2 27/36) * (5/11 + 1/2) = 1 19/36 * (10/22 + 11/22) = 1 19/36 * 21/22 = 55/36 * 21/22 = 35/24 = 1 11/24

Answer 2

To solve the given arithmetic expression, let's break it down step by step:

First, let's simplify the expression inside the parentheses:

(1 4/9 + 2 5/6 - 2 3/4) = (13/9 + 17/6 - 11/4)

To add fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of 9, 6, and 4 is 36. So, we'll convert each fraction to have a denominator of 36:

13/9 = (13/9) * (4/4) = 52/36 17/6 = (17/6) * (6/6) = 102/36 11/4 = (11/4) * (9/9) = 99/36

Now we can add the fractions:

(52/36 + 102/36 - 99/36) = (52 + 102 - 99)/36 = 55/36

Next, let's simplify the expression outside the parentheses:

(5/11 + 10/20) = (20/44 + 22/44) = 42/44

Now, let's multiply the results from inside and outside the parentheses:

(55/36) * (42/44)

To multiply fractions, we multiply the numerators together and the denominators together:

(55/36) * (42/44) = (55 * 42) / (36 * 44) = 2310/1584

Finally, if possible, we can simplify the resulting fraction:

2310/1584 = (2310/6) / (1584/6) = 385/264

So, the final result is 385/264.
