1. **State the problem:** Supriya uses 12 oz of dough to make one batch of papadums. She has 60 oz of dough in total and wants to find out how many batches ($b$) she can make. 2. **Write the equation:** The total dough used is the dough per batch multiplied by the number of batches. $$12 \times b = 60$$ 3. **Solve for $b$:** Divide both sides of the equation by 12 to isolate $b$. $$\cancel{12} \times b = \frac{60}{\cancel{12}}$$ $$b = 5$$ 4. **Interpretation:** Supriya can make 5 batches of papadums with 60 oz of dough. **Final answer:** $b = 5$ batches.
