Answer 1

7/7 = drumul intreg
7/7-4/7=3/7
3/7=12 km
1/7=12:3=4 km
7/7=7x4=28 km drumul intreg
3/7=3x4=12 km a mers
4/7=4x4=16 km i-au ramas de mers
V: 12+16=28 km

Answer 2

7/7-4/7=3/7 a parcurs (adică 12 km). 12 km:3=4 km (1/7). Acum faci 7 segmente si ingorsezi 4. 4 km•4=16 km i-au rămas. Răspuns: 12 km a mers (3/7) si 16 km i-au ramas (4/7).
