Answer 1

O /_____/.........................+39............./
M /_____/..................+25.........../
A /_____/................+21......./

100 - (39+25+21)=100-85=15

1+1+1=3 (segmente egale)

15:3=5 (valoarea unui segment)

Ovidiu=1×5+39=5+39=44 (nuci)

Marian=1×5+25=5+25=30 (nuci)

Alexandra=1×5+21=5+21=26 (nuci)
