Explicație pas cu pas:
ne folosim de regula de trei simpla
a)
2/3 drum ...................... 24 zile
1/3 drum ........................ x zile
=> x = (24*1/3)/2/3 = 8 * 3/2 = 24/2 = 12 zile
b) 2/3 drum ................ 24 zile
3/4 drum ................ x zile
=> x = (24*3/4)/2/3 = 18 * 3/2 = 54/2 = 27 zile
