Proszeeee pomuszcie daje naj za najlepsza odpowiedz.

Answer 1

A )(1i1/5-1/2) + (3/4+3/10)= 

Answer 2

a) (1i1/5-1/2) + (3/4+3/10)= (1,2-0,5)+(0,75+0,3)=0,7+1,05=1,75

c) 3i3/4*2i2/5-4i3/8=15/4*12/5-35/8=9-35/8=9-4,375=4,625

d)10-1i5/6*4i1/2=10-11/6*9/2=10-33/4=10-8,25=1,75

e) 5/7*4i2/3+5/6:1i1/9=5/7*14/3+5/6/10/9=10/3+5/6*9/10=10/3+3/4=40/12+9/12=49/12=4 1/12

f) (2i1/4-1i2/3):(1/6+2/9)=(9/4-5/3)/(3/18+4/18)=(18/12-20/12)/7/18=-2/12*18/7=-36/84
