数学六年级下册能简算的要简算两道
2.7x[1÷(4.3-4.29]
1110÷[48X(6分之5-8分之5)]

(1) =2.7*(1/0.01)=270
(2) =1110/(8*5-5*6)=1110/10=111

1)2.7x[1÷(4.3-4.29)]=2.7×[1÷0.01]=270
2) 1110÷[48X(6分之5-8分之5)]=1110÷(48×5/6 - 48×5/8)=1110÷(40 - 30)=111
解答完毕,谢谢!

2.7× 【1÷{4.3-4.29}]
=2.7×【1÷0.01】
=2.7×100
=270
1110÷{48×6分之5-8分之5)]
=1110÷{40-8分之5]
=1110÷39又8分之3
=1110÷0.375
=2960
