1. Problem Description

The problem asks us to evaluate the expression 115×(23)+1151\frac{1}{5} \times (-\frac{2}{3}) + 1\frac{1}{5}.

2. Solution Steps

First, we convert the mixed numbers to improper fractions.
115=1×5+15=651\frac{1}{5} = \frac{1 \times 5 + 1}{5} = \frac{6}{5}
Now, we rewrite the expression with improper fractions:
65×(23)+65\frac{6}{5} \times (-\frac{2}{3}) + \frac{6}{5}
Next, we perform the multiplication:
65×(23)=6×25×3=1215\frac{6}{5} \times (-\frac{2}{3}) = -\frac{6 \times 2}{5 \times 3} = -\frac{12}{15}
We can simplify the fraction 1215-\frac{12}{15} by dividing both the numerator and the denominator by 3:
1215=12÷315÷3=45-\frac{12}{15} = -\frac{12 \div 3}{15 \div 3} = -\frac{4}{5}
Now we have:
45+65-\frac{4}{5} + \frac{6}{5}
Adding the two fractions:
45+65=4+65=25-\frac{4}{5} + \frac{6}{5} = \frac{-4 + 6}{5} = \frac{2}{5}

3. Final Answer

25\frac{2}{5}
