## Challenge:

The ratio of sugar to flour for cooking a cake is \(\frac{1}{2}\) to 2. What percent of the cake is flour? (Assume that there are only sugar and flour in the cake)

**A-** \(50\%\)

**B-** \(60\%\)

**C-** \(70\%\)

**D-** \(80\%\)

**E-** \(90\%\)

### The Absolute Best Book** to ****challenge your Smart Student!**

The correct answer is D.

The ratio of sugar to flour is \(\frac{1}{2}\) to 2. Therefore, the ratio of the flour to whole is 2 to \(2\frac{1}{2}\) or \(\frac{2}{2\frac{ 1}{2}} = 0.8 = 80\%\)

Therefore, \(80\%\) of the cake is flour.
