1. The problem asks: What is $ \frac{1}{2} $ in $ \frac{3}{5} $? This means we want to find what part of $ \frac{3}{5} $ is $ \frac{1}{2} $. 2. To find this, multiply $ \frac{3}{5} $ by $ \frac{1}{2} $: $$ \frac{3}{5} \times \frac{1}{2} = \frac{3 \times 1}{5 \times 2} = \frac{3}{10} $$ 3. So, $ \frac{1}{2} $ of $ \frac{3}{5} $ is $ \frac{3}{10} $. 4. In other words, $ \frac{1}{2} $ in $ \frac{3}{5} $ equals $ \frac{3}{10} $.
