Oblicz: (3/4+2/3)*6 1 5/6-2*3/4 1 7/10*10+3*1 1/12 Gwiazdka to razy daje naj podreńcznik Nowa Matematyka Z Plusem Plis!!!!Na Jutro!!

(3/4 + 2/3) × 6 = (9/12 + 8/12) + 6 = 17/12 × 6 = 17/2 = 8 1/2 = 8,5 1 5/6 - 2 × 3/4 = 11/6 - 3/2 = 11/6 - 9/6 = 2/6 = 1/3 1 7/10 × 10 + 3 × 1 1/12 = 17/10 × 10 + 3 × 13/12 = 17 + 13/4 = 17/1 + 13/4 = 17/4 + 13/4 = 30/4 = 7 2/4 = 7 1/2 = 7,5

(3/4+2/3)*6=(9/12+8/12)*6=17/12*6=17/2=8 1/2 1 5/6-2*3/4=11/6-3/2=11/6-9/6=2/6=1/3 1 7/10*10+3*1 1/12=17/10*10+3*13/12=17+13/4=68/4+13/4=81/4=20 1/4
