a.) 12-3-4+5-/-6/+7+/+89/= b.) -(+4)-/12-8/:(/-2+5/-/-1/) / inseamna modul
Efectuați : a) (5/4 - 7/12) : 2/5 - 4/3 b) 7/6 - 3/11*(2/9 - 5/6) c) (13/8 - 7/12) : 5/6 - 3/2
Efectuati fractiile: -5/6+3/8; -1/6+5/12; 13/18+(-5/6); -7/12+(-3/4), Va rog, repede.
(12 5/12 + 1 2/3 - 3 5/6+2 3/4): (2 1/2 ×2/5 - 7/9)
