Explicație pas cu pas:
a) [tex]\frac{3}{5} * 1 leu = \frac{3}{5} * 100 bani = \frac{3*100}{5} = \frac{300}{5} = 60 bani[/tex]
b) [tex]\frac{7}{10} * 100 lei = \frac{700}{10} = 70 lei[/tex]
c) [tex]\frac{1}{12} * 1 an = \frac{1}{12} * 12 luni = \frac{12}{12} = 1 luna[/tex]
d) [tex]\frac{4}{7} * 1 saptamana = \frac{4}{7} * 7 zile = \frac{28}{7}= 4 zile[/tex]
e) [tex]\frac{5}{6} * 1 ora = \frac{5}{6} * 60 minute = \frac{5*60}{6} = 50 minute[/tex]
f) [tex]\frac{3}{4} * 1 zi = \frac{3}{4} * 24 ore = \frac{3*24}{4} = 18 ore[/tex]
g) [tex]\frac{3}{10} * 1m = \frac{3}{10} * 10 dm = 3 dm[/tex]
h) [tex]\frac{1}{4} * 1 km = \frac{1}{4} * 1000 m = \frac{1000}{4} = 250 m[/tex]
i) [tex]\frac{2}{5} * 1 kg = \frac{2}{5} * 1000 g = \frac{2000}{5} = 400 g[/tex]
j) [tex]\frac{5}{8} * 1 tona = \frac{5}{8} * 1000 kg = \frac{5000}{8 } = 625 kg[/tex]
k) [tex]\frac{9}{9} * 1 l = 1 l[/tex]
l) [tex]\frac{6}{6} * 1 kg = 1 kg[/tex]
