Charra [1.4K]

Answer:

The ratio of the number of cows to the number of sheeps in the farm is;

$\begin{gathered} \frac{4}{5} \\ Or \\ 4\colon5 \end{gathered}$

Explanation:

Given that;

there were 75 sheep

and 60 cows

We want to find the ratio of the number of cows to the number of sheeps in the farm;

$\text{ratio}=\frac{\text{ number of cows }}{\text{ number of sh}eeps}=\frac{60}{75}$

reducing the ratio to the least form;

$\text{ratio=}\frac{60}{75}=\frac{4}{5}$

Therefore, the ratio of the number of cows to the number of sheeps in the farm is;

$\begin{gathered} \frac{4}{5} \\ Or \\ 4\colon5 \end{gathered}$

Each friend got 6 erasers.
