Question

dupa ce au sapat 3 supra 5 dintr-un sant,nuste muncitori constata ca mai au de sapat inca 4 metri.catimetri are intregul sant?cati metri au sapat?

Answer 1

$1- \frac{3}{5} = \frac{2}{5}$
$\frac{2}{5}$ este 4 metri
$4: \frac{2}{5} = \frac{4}{1} : \frac{2}{5} = \frac{4}{1} *\frac{5}{2} = \frac{10}{1} =10 metri$ are santul
10-4=6m au sapat
