0.45×10=	0.68+3.2=	0.5×0.2=	7.8÷10=
7.5-2.4=	6.3÷3=	5.6×3=	(7)/(9)−(2)/(9)=
(3)/(10)+(3)/(10)=	(1)/(5)+(2)/(5)=	0.69÷100=	0.56÷10=

Answer 1

0.45×10=4.5	0.68+3.2=3.88	0.5×0.2=0.1	7.8÷10=0.78
7.5-2.4=5.1	6.3÷3=2.1	5.6×3=16.8	(7)/(9)−(2)/(9)=(5)/(9)
(3)/(10)+(3)/(10)=(3)/(5)	(1)/(5)+(2)/(5)=(3)/(5)	0.69÷100=0.0069	0.56÷10=0.056
