The chef 2

A chef used 19/20 cups of chocolate chips and 1 1/10 cups of cocoa powder for a cake. How much more cocoa powder did the chef use than chocolate chips?

Final Answer:

x =  3/20

Step-by-step explanation:

$$\begin{gathered} c=\frac{19}{20}=0.95 \\ p=1\frac{1}{10}=1+\frac{1}{10}=\frac{1\cdot 10+1}{10}=\frac{10+1}{10}=\frac{11}{10}=1\frac{1}{10}=1.1 \\ x=p-c=\frac{11}{10}-\frac{19}{20}=\frac{22}{20}-\frac{19}{20}=\frac{22-19}{20}=\frac{3}{20}=0.15 \end{gathered}$$
