Q:

Finding the number of newspapers

A certain school has 300 students every student reads 5 newspapers and every newspaper is read by 60 students then find the number of newspapers?

A:

$300 \cdot 5 = 1500$ "readings"
Numbers of "readings" = $n \cdot 60$
where $n$ ist the number of newspapers.
So $60 n = 1500$ and therefore $n = 25$
