Question

1/6*(6.75/12分之5-2.4+4又四分之一*二又五分之二)-一又八分之一-0.875？

Answer 1

1/6×(6.75÷5/12-2.4+4又1/4×2又2/5)-1又1/8-0.875
=1/6×(27/4×12/5-12/5+17/4×12/5)-9/8-7/8
=1/6×12/5×(27/4-1+17/4)-(9/8+7/8)
=1/6×12/5×10-2
=4-2
=2
9999×2222+3333×3334
=3333×(3×2222)+3333×3334
=3333×6666+3333×3334
=3333×(6666+3334)
=3333×10000
=33330000
(1×3×24+2×6×48+3×9×72)/(1×2×4+2×4×8+3×6×12)
=1×3×24×(1+2×2×2+3×3×3)/[1×2×4×(1+2×2×2+3×3×3)]
=(1×3×24)/(1×2×4)
=9,8,1/6*(6.75/12分之5-2.4+4又四分之一*二又五分之二)-一又八分之一-0.875
9999*2222+3333*3334=
（1*3*24+2*6*48+3*9*72）/（1*2*4+2*4*8+3*6*12）=
