Answer 1

a) 1leu=100 bani
$\frac{3}{5}$× 100 bani= $\frac{300}{5}$ bani =60 bani
$\frac{7}{10}$× 100 lei= $\frac{700}{10}$ lei= 70 lei
b) 1 an=12 luni
$\frac{1}{12}$× 12 luni= 1 luna
1 saptamana= 7 zile
$\frac{4}{7}$× 7 zile=$\frac{28}{7}$ zile= 4 zile
c) 1 ora= 60 minute
$\frac{5}{6}$× 60 min=$\frac{300}{6}$ min= 50 min
1 zi= 24 ore
$\frac{3}{4}$× 24 ore= $\frac{72}{4}$ ore= 18 ore
