Salut! :D
a) 3/5 din 2015:
1) Transformam "din" in inmultire: [tex]\frac{3}{5}[/tex] × 2015.
2) Scriem 2015 ca 2015/1: [tex]\frac{3}{5}[/tex] × [tex]\frac{2015}{1}[/tex].
3) Efectuam inmultirea: [tex]\frac{3}{5}[/tex] × [tex]\frac{2015}{1}[/tex] = 1209.
b) 17/20 din 10160:
1) Transformam "din" in inmultire: [tex]\frac{17}{20}[/tex] × 10160.
2) Scriem 10160 ca 10160/1: [tex]\frac{17}{20}[/tex] × [tex]\frac{10160}{1}[/tex].
3) Efectuam inmultirea: [tex]\frac{17}{20}[/tex] × [tex]\frac{10160}{1}[/tex] = 8636.
Sper ca te-am ajutat! :)
