(0.75-3/16)*(2/9+1/3)= 18/35除以0.6*2/3= 35/64除以(1/8+3/4)=

(0.75-3/16)*(2/9+1/3)= 18/35除以0.6*2/3= 35/64除以(1/8+3/4)=
(0.75-3/16)*(2/9+1/3)= 18/35除以0.6*2/3= 35/64除以(1/8+3/4)=

(0.75-3/16)*(2/9+1/3)= 18/35除以0.6*2/3= 35/64除以(1/8+3/4)=
(0.75-3/16)*(2/9+1/3)= (12/16-3/16)*(2/9+3/9)
=(9/16)*(5/9)=5/16
18/35除以0.6*2/3=(18/35)*(5/3)*(2/3)=4/7
35/64除以(1/8+3/4)=(35/64)÷(7/8)=(35/64)*(8/7)=5/8

(0.75-3/16)*(2/9+1/3)= (3/4-3/16)*(2/9+3/9)=9/16 * 5/9=5/16
18/35除以0.6*2/3= 18/35 * 3/5 * 2/3=4/7
35/64除以(1/8+3/4)= 35/64 * 8/7=5/8
