41/6*(1 1/2-3/5)+(3/4+5/6)*6 , , решить по действиям.

4(1/6)×((11/2)-(3/5))+((3/4)+(5/6))×6=13(1/4)=13,25

1) 1(1/2)-(3/5)=(3/2)-(3/5)=(3×5-3×2)/10=(15-6)/10=9/10

2) (3/4)+(5/6)=(3×3+5×2)/12=(9+10)/12=19/12

3) (9/10)×4(1/6)=9/10×25/6=(3×3×5×5)/(2×5×3×2)=15/4

4) 19/12×6=114/12

5) 15/4+114/12=(15×3+114)/12=(45+114)/12=(159/12)=13(3/12)=13(1/4)=13,25
