Question

口算 (5)/(6) × (9)/(10) =	(24)/(19) ÷8=	0.375× (4)/(9) =	4.2+ (3)/(5) =	24÷ (3)/(8) =
3×3×3=	63×10%=	1.5×0.4=	3.14×6=	0.18÷3=

Answer 1

(5)/(6) × (9)/(10) = (3)/(4) ，	(24)/(19) ÷8= (3)/(19) ，	0.375× (4)/(9) = (1)/(6) ，	4.2+ (3)/(5) =4.8，	24÷ (3)/(8) =64，
3×3×3=27，	63×10%=6.3，	1.5×0.4=0.6，	3.14×6=18.84，	0.18÷3=0.06．
