Question

A cow yields $12\frac{3}{5}$ liters of milk in a day. How much milk does she yield in a week?

Answer 1

Milk yielded in one day = $12\frac{3}{5}$liters

In one week we have $7$days

So, milk yielded by a cow in a week =

$$\begin{gathered} 12\frac{3}{5}\times 7=\frac{63}{5}\times 7 \\ \frac{441}{5}=88\frac{1}{5}liters \end{gathered}$$

Hence the answer is $88\frac{1}{5}liters$.
