Answer 1

1) =(5ц15/15 - 4ц8/15):2,2= 1ц7/15:2ц2/10=22/15:22/10= Дальше общая черта: в числителе 22*10 в знаменателе 15*22 (22 сокращаються, 10 и 15 сокращаються на 5)= 3/2=1ц1/2=1,5Напишите в ответе здесь

Answer 2

Calculation of the Expression

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

1. Step 1: Calculate the expression within the parentheses: (6 + целых - 4 целых 8/15).

- The expression within the parentheses can be simplified as follows: - 6 + целых - 4 целых 8/15 = 6 - 4 + 8/15 = 2 + 8/15.

2. Step 2: Calculate the expression within the parentheses: (5,4 - 2 целых 1/3).

- The expression within the parentheses can be simplified as follows: - 5.4 - 2 целых 1/3 = 5.4 - 2 - 1/3 = 3.4 - 1/3.

3. Step 3: Calculate the expression within the parentheses: (целых 2/3 3).

- The expression within the parentheses can be simplified as follows: - целых 2/3 3 = 2/3 * 3 = 2.

4. Step 4: Calculate the expression within the parentheses: (7.6 - 4 целых 3/4).

- The expression within the parentheses can be simplified as follows: - 7.6 - 4 целых 3/4 = 7.6 - 4 - 3/4 = 3.6 - 3/4.

5. Step 5: Calculate the final expression: (2 + 8/15) / (2.2 + 2) / (3.4 - 1/3) / (2/3 * 3) / (3.6 - 3/4) / 1.9.

- To calculate this expression, we need to perform the operations in the following order: division, addition, and subtraction. - Let's calculate the expression step by step:

- (2 + 8/15) = 2 + (8/15) = 2 + 0.5333 = 2.5333. - (2.2 + 2) = 2.2 + 2 = 4.2. - (3.4 - 1/3) = 3.4 - (1/3) = 3.4 - 0.3333 = 3.0667. - (2/3 * 3) = (2/3) * 3 = 0.
