kvasek [131]

The fraction of the fence completed in one hour at a rate of $\frac{2}{5}$ of the

fence in $\frac{3}{4}$ hours is $\frac{8}{15}$ .

<h3>How can the fraction completed in one hour be found?</h3>

The fraction of the fence completed in $\mathbf{\frac{3}{4}}$ of an hour = $\frac{2}{5}$

Required:

The fraction of the fence the student completes per hour;

Solution;

The time $\mathbf{\frac{2}{5}}$ of the fence is completed = $\frac{3}{4}$ of an hour

Therefore;

$The \ in \ \mathbf{\frac{\dfrac{3}{4} \ hour}{\dfrac{3}{4} \ hour}} = 1 \ hour \ the \ frraction \ completed = \dfrac{\dfrac{2}{5} }{\dfrac{3}{4} \ hour} = \dfrac{8}{15} \ per \ hour$
