Answer 1

2\3*(1 целая 1\2х+3\5)-0.8-(5\12х-1\2)= 7\12х+1\10

Answer 2

Simplifying the Expression

To simplify the given expression 2/3*(1+1/2*x+3/5)-0.8-(5/12*x-1/2), we can follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Distribute the 2/3

First, we distribute the 2/3 across the terms inside the parentheses: 2/3 * 1 + 2/3 * 1/2x + 2/3 * 3/5 - 0.8 - 5/12x + 1/2

Step 2: Perform Multiplication and Addition

Next, we perform the multiplications and additions within the expression: 2/3 + 1/3x + 2/5 - 0.8 - 5/12x + 1/2

Step 3: Combine Like Terms

Now, we combine like terms: 2/3 - 0.8 + 1/3x - 5/12x + 2/5 + 1/2

Step 4: Simplify Further

Finally, we simplify the expression: -0.133333 + 0.0833333x

So, the simplified expression is -0.133333 + 0.0833333x.
