Răspuns :
1. Rațele=58 x 2=116
găini=10000:4=2500
Capre=75:3=25.
Lungimea 7/5=1 întreg și 2/5
1 întreg =5m 2/5=2 m
Lățimea =7 m
P=7 x 5=35
35m x 2=70 m.

1) rate=58x2=116
gaini=10000:4=2500
capre=75x3=225
116+2500+225=2866 animale
2) l=5m
L=7/5 din l
7/5(5)=7/5x5/5 =35/5 =7m
Lx l => 7x5=35m
35x2=70m sarma
3) 40 se imparte la 1;2;4;5;10.20; 40
40:(0+1)......a=0..........40:1
