Question

直接写得数

9.09+1.1=	10÷0.1=	3-1.45=	5-1.4-1.6=
1÷0.25×4=	1÷（(1)/(2)-(1)/(3)）=	(2)/(3)×(9)/(4)×(1)/(2)=	4-(2)/(3)-(1)/(3)=
(4)/(9)-(4)/(9)÷4=	5÷(1)/(5)-(1)/(5)÷5=	302×59≈	3.16+11.8+5.01≈
4230÷71≈	18.5×2.2≈

Answer 1

9.09+1.1=10.19	10÷0.1=100	3-1.45=1.55	5-1.4-1.6=2
1÷0.25×4=16	1÷（(1)/(2)-(1)/(3)）=6	(2)/(3)×(9)/(4)×(1)/(2)=(3)/(4)	4-(2)/(3)-(1)/(3)=3
(4)/(9)-(4)/(9)÷4=(1)/(3)	5÷(1)/(5)-(1)/(5)÷5=24(24)/(25)	302×59≈18000	3.16+11.8+5.01≈20
4230÷71≈60	18.5×2.2≈40
