1. **State the problem:** We are given that one serving of wheat square cereal has 3 grams of fiber, which is 19% of the recommended daily amount. We need to find the total recommended daily amount of fiber. 2. **Formula used:** If $x$ is the total recommended daily amount of fiber, then 19% of $x$ equals 3 grams. This can be written as: $$0.19 \times x = 3$$ 3. **Solve for $x$:** $$x = \frac{3}{0.19}$$ 4. **Intermediate step with cancellation:** $$x = \frac{3}{\cancel{0.19}} \times \frac{1}{\cancel{1}} = \frac{3}{0.19}$$ 5. **Calculate the value:** $$x = 15.78947368...$$ 6. **Round to the nearest tenth:** $$x \approx 15.8$$ **Final answer:** The total recommended daily amount of fiber is approximately 15.8 grams.
