Answer 2

Ответ:

(3.25 + 2 2/3 ) ÷ (9 1/2 - 2.4) × 1 1/5 = 1

Answer 3

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

Step 1: Convert mixed numbers to improper fractions: 2 целых 2/3 = (2 * 3 + 2) / 3 = 8/3 9 целых 1/2 = (9 * 2 + 1) / 2 = 19/2 1 целая 1/5 = (1 * 5 + 1) / 5 = 6/5

Step 2: Simplify the expression inside the parentheses: (3,25 + 8/3) / (19/2 - 2,4) * 6/5

Step 3: Perform addition and subtraction within the parentheses: 3,25 + 8/3 = 3,25 + 8/3 = 3,25 * 3/3 + 8/3 = (9,75 + 8) / 3 = 17,75/3

19/2 - 2,4 = 19/2 - 2,4 * 2/2 = 19/2 - 4,8/2 = (19 - 4,8) / 2 = 14,2/2

Step 4: Simplify the expression outside the parentheses: (17,75/3) / (14,2/2) * 6/5

Step 5: Simplify the division and multiplication: (17,75/3) / (14,2/2) = (17,75/3) * (2/14,2) = (17,75 * 2) / (3 * 14,2) = 35,5 / 42,6 = 0,8343

0,8343 * 6/5 = (0,8343 * 6) / 5 = 5,0058 / 5 = 1,0012

Therefore, the value of the given expression is approximately 1,0012.
