Daca 75%.......................24 km
100%..............................x km
x=(100×24) : 75=32 km
100%..............................x km
x=(100×24) : 75=32 km
x= lungime tr.
x - 75% din x =24
x- 75/100* x=24
x - 3/4 *x= 24
1/4 *x =24
x= 24 :1/4
x=24*4=96
x - 75% din x =24
x- 75/100* x=24
x - 3/4 *x= 24
1/4 *x =24
x= 24 :1/4
x=24*4=96
