cu secmente
dau coruana​

Answer 1

a,b,c,d= cele patru bidoane

b=a:2  => a=2b

c=b:2  => b=2c

d=c:2  => c=2d

2b+2c+2d+d=2250

2x2c+2x2d+3d=2250

4c+4d+3d=2250

4x2d+4d+3d=2250

8d+4d+3d=2250

15d=2250

d=2250:15  => d=150 litri

c=2d  => c=2x150  => c=300 litri

b=2c  => b=2x300  => b=600 litri

a=2b  => a=2x600  => a=1200 litri

a+b+c+d=2250  => 1200+600+300+150=2250 litri

nu stiu ce inseamna secmente ( poate segmente dar secmente nu )
