a) 1 timp + 1/2 timpi +1/2 timpi + 1 timp = 3 timpi .
adica patrime + cele doua optimi + patrime.
b) 2 timpi + 1/2 timpi + 1/2 timpi = 3 timpi .
adica doime + cele doua optimi
c)1 timp + 1/4 timpi + 1 timp + 3/4 timpi = 3 timpi
adica patrime + saisprezecime + patrime + optime cu punct
d)1 1/2 timpi + 1/2 timpi + 2 timpi = 3 timpi
adica patrime cu punct + optime + doime
e)2 timpi + 1 timp = 3 timpi
adica doime + patrime
f)4 x 1/4 timpi + 2 timpi = 3 timpi
adica 4 saisprezecimi + o doime
