(-7/24)÷(-14/+51)x(+19/-34)
=(-7/24)x(-51/14)x(+19/-34)
=-(7/24)x(51/14)x(19/34)
==-(1/8)x(1/2)x(19/2)
=-19/32
=(-7/24)x(-51/14)x(+19/-34)
=-(7/24)x(51/14)x(19/34)
==-(1/8)x(1/2)x(19/2)
=-19/32

(-7/24)÷(-14/+51)x(+19/-34)
= - ( (7/24) / (14/51) x (19/34) ) <= 先抽負
= - ( 7/24 x 51/14 x 19/34 ) <=除轉乘
= - (1/8 x 1/2 x 19/2) <=相約
= - 19/32
= - ( (7/24) / (14/51) x (19/34) ) <= 先抽負
= - ( 7/24 x 51/14 x 19/34 ) <=除轉乘
= - (1/8 x 1/2 x 19/2) <=相約
= - 19/32
