Question

2 3/4 : (1 1/2-0.4)+(0.75+3 1/9 : 2 1/3 : 6 3/4 * 9/16)=распишите пожайлуста подробно решение! Заранее благодарны!

Answer 1

1) 1 1/2 - 0,4 = 1,5-0,4 = 1,1 = 11/10

2) 2 3/4 : 11/10 = 11/4 : 11/10 = 11/4 * 10/11 = 5/2 = 2 1/2

3) 3 1/9 : 2 1/3 : 6 3/4 * 9/16 = 28/9 * 3/7 * 4/27 * 9/16 = 1/9

4) 2 1/2 + 1/9 = 2 (9+2)/18 = 2 11/18

Answer 2

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

Step 1: Simplify the expression inside the parentheses: (1 + 1/2 - 0.4) = 1.1 (0.75 + 3 + 1/9) = 3.9167 (2 + 1/3 + 6 3/4 * 9/16) = 2.3333 + 6.75 * 0.5625 = 2.3333 + 3.7969 = 6.1302

Step 2: Substitute the simplified values back into the original expression: 2 3/4 : 6.1302 = 2.75 : 6.1302

Step 3: Divide the numerator by the denominator: 2.75 / 6.1302 = 0.4485

Therefore, the solution to the given expression is approximately 0.4485.

Please note that the above solution is based on the provided expression and the calculations performed.
