Question

直接写出得数，我最棒．

30×5=	120×4=	42÷6=	530+70=
320+450=	700×0=	101×7=	31÷5=
75+0=	310-107=	303×8≈	53×6≈
2100×4≈	81÷9=	704-500=	(1)/(5)+(2)/(5)=
(1)/(6)+(5)/(6)=	(7)/(8)-(3)/(8)=	1-(1)/(4)=	(1)/(3)+(2)/(3)=

Answer 1

30×5=150	120×4=480	42÷6=7	530+70=600
320+450=770	700×0=0	101×7=707	31÷5=6…1
75+0=75	310-107=203	303×8≈2400	53×6≈300
2100×4≈8000	81÷9=9	704-500=204	(1)/(5)+(2)/(5)=(3)/(5)
(1)/(6)+(5)/(6)=1	(7)/(8)-(3)/(8)=(1)/(2)	1-(1)/(4)=(3)/(4)	(1)/(3)+(2)/(3)=1
