Question

$\frac{5}{10}$ the number of cows is the same as $\frac{4}{5}$ the number of sheeps. If there are $425$ sheeps, find the total number of cows and sheeps.

Answer 1

Let $x$ be the number of cows and $y$ be the number of sheeps

Then

$\left(\frac{5}{10}\right)x=\left(\frac{4}{5}\right)y$

$\left(\frac{5}{10}\right)x=\left(\frac{8}{10}\right)y$

$5x=8y$

Number of sheeps$=425$

Then,

$5x=8\times 425$

$x=\frac{3400}{5}$

$x=680$
