Question

A total of 250 households were surveyed. What fraction of the total number of households have three televisions?

Answer 1

Let:

N = Total households = 250

r = Percentage of households that have 3 televisions = 24 % = 0.24

The fraction of the total number of households have three televisions, is:

`\begin{gathered} N\cdot r=250\cdot0.24 \\ where\colon \\ 0.24=(6)/(25) \\ 250\cdot(6)/(25)=(1500)/(25)=60 \end{gathered}`

60 households have 3 televisions
