Answer 1

1 1/3у+0,48-1/3у+0,48=у+0,96

Answer 2

Simplifying the Expression

To simplify the given expression, we start by substituting the value of y into the expression and then performing the operations step by step.

The given expression is: 0.8 + (1 + 2/3y - 0.6) - 0.6(5/9y - 0.8)

Substitute the value of y: 0.8 + (1 + 2/3*0.5 - 0.6) - 0.6(5/9*0.5 - 0.8)

Now, let's calculate the values step by step.

Calculating the Expression

1. Calculate the value of 2/3*0.5: 2/3*0.5 = 1/3

2. Calculate the value of 5/9*0.5: 5/9*0.5 = 5/18

3. Substitute the calculated values back into the expression: 0.8 + (1 + 1/3 - 0.6) - 0.6(5/18 - 0.8)

4. Perform the operations within the parentheses: 0.8 + (1.33 - 0.6) - 0.6(-0.2778 - 0.8)

5. Continue simplifying: 0.8 + 0.73 - 0.6*(-1.0778)

6. Calculate the value of -0.6*(-1.0778): 0.8 + 0.73 + 0.64668

7. Add the values together: 0.8 + 0.73 + 0.64668 = 2.17668

Result

The simplified value of the expression 0.8 + (1 + 2/3y - 0.6) - 0.6(5/9y - 0.8) is 2.17668.
