Answer 1

ДАНО
(3 4/9 - 1 11/12)*3 9/11 + 6 : 12/25 - 2 1/3 = 16 = ?
По действиям
3 4/9 - 1 11/12 =1 19/36
1 19/36 * 3 9/11 =  5 5/6
6 : 12/25 = 12 1/2
5 5/6 + 12 1/2 = 18 1/3
18 1/3 - 2 1/3 = 16 - ПРАВИЛЬНО

Answer 2

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

(3 + 4/9 - 1 + 11/12) * 3 + 9/11 + 6 ÷ 12/25 - 2 + 1/3

Step 1: Simplify within parentheses

Inside the parentheses, we have addition and subtraction of fractions. To simplify, we need to find a common denominator for the fractions.

The common denominator for 9 and 12 is 36. So, we can rewrite the expression as:

(3 * 36/36 + 4/9 * 4/4 - 1 * 36/36 + 11/12 * 3/3) * 3 + 9/11 + 6 ÷ 12/25 - 2 + 1/3

Simplifying further:

(108/36 + 16/36 - 36/36 + 33/36) * 3 + 9/11 + 6 ÷ 12/25 - 2 + 1/3

Step 2: Combine like terms

Now, let's combine the fractions with the same denominator:

(108 + 16 - 36 + 33)/36 * 3 + 9/11 + 6 ÷ 12/25 - 2 + 1/3

Simplifying further:

(121/36) * 3 + 9/11 + 6 ÷ 12/25 - 2 + 1/3

Step 3: Perform multiplication and division

Next, let's perform the multiplication and division operations:

(121/36) * 3 + 9/11 + (6 ÷ 12/25) - 2 + 1/3

Simplifying further:

**(121/36) * 3 + 9/11 + (6 * 25/12) -
