1. **State the problem:** We need to find how many cereal brands have less than $\frac{1}{4}$ grams of sodium per cup. 2. **Identify the sodium content for each brand:** - Crispee Flakes: 0.23 grams - Corn Puffers: 0.28 grams - Energy Doodles: 0.26 grams 3. **Convert $\frac{1}{4}$ to decimal:** $$\frac{1}{4} = 0.25$$ 4. **Compare each brand's sodium content to 0.25 grams:** - Crispee Flakes: $0.23 < 0.25$ (less than $\frac{1}{4}$) - Corn Puffers: $0.28 > 0.25$ (not less than $\frac{1}{4}$) - Energy Doodles: $0.26 > 0.25$ (not less than $\frac{1}{4}$) 5. **Count the brands with less than $\frac{1}{4}$ grams:** Only Crispee Flakes meets the condition. **Final answer:** Only 1 brand has less than $\frac{1}{4}$ grams of sodium per cup.
