Internet households

There are 600 households in a certain village. Last year, three-fifths of them had an Internet connection. This year, the number of households connected to the Internet increased by 40. What proportion of households has an Internet connection this year?

Final Answer:

x =  0.6667

Step-by-step explanation:

$$\begin{gathered} n=600 \\ i=\frac{3}{5}\cdot 600=\frac{3\cdot 600}{5}=\frac{1800}{5}=360 \\ x=\frac{i+40}{n}=\frac{360+40}{600}=\frac{2}{3}=0.6667 \end{gathered}$$
