On Monday 3

On Monday, James had a pizza for lunch. He only ate 2/3 and left the rest for supper. At supper, he only had 1/2 of the pizza that was left over from lunch. How much does he have left after supper

Final Answer:

x =  1/6

Step-by-step explanation:

$$\begin{gathered} a=\frac{2}{3}\doteq 0.6667 \\ b=1-\frac{2}{3}=\frac{1\cdot 3}{3}-\frac{2}{3}=\frac{3}{3}-\frac{2}{3}=\frac{3-2}{3}=\frac{1}{3}\doteq 0.3333 \\ c=\frac{1}{2}\cdot b=\frac{1}{2}\cdot \frac{1}{3}=\frac{1\cdot 1}{2\cdot 3}=\frac{1}{6}\doteq 0.1667 \\ x=b-c=\frac{1}{3}-\frac{1}{6}=\frac{2}{6}-\frac{1}{6}=\frac{2-1}{6}=\frac{1}{6}=0.1667 \end{gathered}$$
