Rezolvati-le va rog :)))

Answer 1

b)(1+3/2×5/2):6-1=
=(1+15/4):6-1=
=(4+15)/24-1=
=19/24-1=(19-24)/24=-5/24

c)(12/35-7/20)(-1-1/6)=
=(48-49/140)(-6-1)/6=
=(-1/140)(-7/6)=
=1/120

d)(6/32+5/24)×30/38-1/8=
=(18+20)/96)×15/19-1/8=
=38/96 ×15/19-1/8=
=19/48 ×15/19-1/8=
=5/16 -1/8=
=(5-2)/16=3/16

e)3-2:(5/8×12/15)+(1/3)²=
=3-2:1/2+1/9=
=3-4+1/9=
=-1+1/9=
=(-9+1)/9=-8/9

f)5/6:1/3:(12/8-5/6)=
=5/6 ×3:(3/2-5/6)=
=5/2:(9-5)/6=
=5/2:4/6=
=5/2:2/3=
=5/2×3/2=15/4
