Question

脱式计算。谢谢，每道题要过程做出来，急急急。

(1)(2分之1＋3分之1＋4分之1＋6分之1)×48

(2)0.7×36.5＋0.7×64.5－0.7

Answer 1

您好：

(1)(2分之1＋3分之1＋4分之1＋6分之1)×48
=1/2x48+1/3x48+1/4x48+1/6x48
=24+16+12+8
=40+20
=60

(2)0.7×36.5＋0.7×64.5－0.7
=0.7x(36.5+64.5-1)
=0.7x100
=70

如果本题有什么不明白可以追问，如果满意记得采纳
如果有其他问题请采纳本题后另发点击向我求助，答题不易，请谅解，谢谢。
祝学习进步！

Answer 2

(1)(2分之1＋3分之1＋4分之1＋6分之1)×48
=2分之1x48+3分之1x48+4分之1x48+6分之1x48
=24+16+12+8
=60

(2)0.7×36.5＋0.7×64.5－0.7
=0.7x（36.5+64.5-1）
=0.7x100
=70

有不明白的可以追问！谢谢！！
祝学习进步！

Answer 3

(1)(2分之1＋3分之1＋4分之1＋6分之1)×48
=48×(1/2)+48×(1/3)+48×(1/4)+48×(1/6)
=24+16+12+8
=40+20
=60;
(2)0.7×36.5＋0.7×64.5－0.7
=0.7×(36.5+64.5-1)
=0.7×100
=70;

Answer 4

(1)(1/2+1/3+1/4+1/6)×48
=24+16+12+8
=60
(2)0.7×36.5+0.7×64.5-0.7
=0.7×(36.5+64.5-1)
=0.7×100
=70

Answer 5

（1)=2分之1×48+3分之1×48+4分之1×48+6分之1×48=24+16+12+8=60
（2）=0.7*（36.5+64.5-1）=0.7*100=70
