1. **State the problem:** We want to find out how many pigs can share 3 blocks if each pig gets $\frac{1}{2}$ of a block. 2. **Formula used:** To find the number of pigs, divide the total number of blocks by the amount each pig gets: $$\text{Number of pigs} = \frac{\text{Total blocks}}{\text{Blocks per pig}}$$ 3. **Apply the values:** $$\text{Number of pigs} = \frac{3}{\frac{1}{2}}$$ 4. **Simplify the division by a fraction:** $$\frac{3}{\frac{1}{2}} = 3 \times \frac{2}{1}$$ 5. **Calculate the multiplication:** $$3 \times 2 = 6$$ 6. **Answer:** So, 6 pigs can share 3 blocks if each pig gets half a block.
