How many liters of flour does Bao use per liter of water? 1 liters
Graph: a line with positive slope on a coordinate grid, starting at the origin and passing through the point (3, 1); position_hint = center
1. **State the problem:** We want to find the relationship between liters of water and liters of flour used by Bao.
2. **Given information:**
- Bao uses 3 liters of water per liter of flour.
- Bao uses 1 liter of flour per liter of water.
3. **Expressing the relationship:**
- Let $f$ be liters of flour and $w$ be liters of water.
- From the first statement, $w = 3f$.
- From the second statement, $f = 1w$ or $f = w$.
4. **Check consistency:**
- If $w = 3f$, then $f = \frac{w}{3}$.
- The second statement says $f = w$, which contradicts the first unless we interpret it as per liter of water, Bao uses 1 liter of flour, meaning $f = w$.
5. **Resolving the contradiction:**
- The first statement means for each 1 liter of flour, Bao uses 3 liters of water.
- The second means for each 1 liter of water, Bao uses $\frac{1}{3}$ liters of flour.
6. **Graph interpretation:**
- The line passes through $(3,1)$ meaning at $w=3$, $f=1$.
- Equation of the line is $w = 3f$ or equivalently $f = \frac{w}{3}$.
7. **Final answers:**
- Bao uses $\boxed{3}$ liters of water per liter of flour.
- Bao uses $\boxed{\frac{1}{3}}$ liters of flour per liter of water.
