25*40/100=10 baieti
2)
1400*10/100=140
3)
4 muncitori.....12 ore
3 muncitori...y ore => y= 12*4/3=16

[tex]1) \ 40 \% \ din \ 25 \ = \frac{40}{100} *25 = \frac {4}{10} *25 = \frac{2}{5} *25 = 2*5 =10 \ baieti \ \\ 2) 10 \% \ din \ 1400= \frac{10}{100} *1400= \frac{1}{10} *1400= 140 \\ 3) 4m.............12h \\ 3m.................x \\ x=\frac{4*12}{3} \ sunt \ marimi \ invers \ proportionale \ \\ x= 4*4 \\ x= 16h[/tex]
