"If a 3/4-cup serving of cereal provides your full daily value of vitamin B6, then what percentage of your daily value of vitamin B6 will you receive in 1/2 of a cup of cereal? First, solve the problem with the aid of either a picture, a percent diagram or both, explaining your reasoning. Then, solve the problem by setting up and solving an equation."

Hello,

Let P be the percentage of daily value contained in 1/2 of the cup.

3/4 cup ---------> 100%
1/2 cup ---------> P%

Then : \frac{\frac 12}{\frac 34}=\frac{P}{100}

--------> \frac 1{\not 2} \cdot \frac{\not 4^2}{3}=\frac{P}{100}

-------------> \frac 23=\frac{P}{100}


\boxed{P=\frac{200}{3} \approx 66.67}
