Answer 1

1) a) [3/4+2/3:1/4]×6/41 =

= (3/4+2/3×4)×6/41=

=(3/4+8/3)×6/41=

=(9/12+32/12)×6/41=

=41/12×6/41=

=1/2

b) [7/5:14/15+3/2:(9/4-3/2)]×2/7=

=[7/5:14/15+3/2:3/4]×2/7=

=(7/5×15/14+3/2×4/3)×2/7=

=(3/2+2)×2/7=

=7/2×2/7=

=1

c) [17/3+14/9-2]:47/3=

=[51/9+14/9-18/9]:47/3=

=47/9:47/3=

=47/9×3/47=

=1/3

d) [4+20/3-9/4(2/3-2/9)]:29/6+29/4=

=[4+20/3-9/4×4/9]:29/6+29/4=

=[4+20/3-1]:29/6+29/4=

=[12+20-3/3]:29/6+29/4=

=29/3:29/6+29/4=

=29/3×6/29+29/4=

=2+29/4=

=8+29/4=

=37/4=

=9.25
