10÷10/13脱式计算
10÷10/13脱式计算
10÷10/13
=10×13/10
=13
10/7-8/3-8/1=?(脱式计算)
10/7-8/3-8/1
=10/7-(8/3+8/1)
=10/7-2/1
=10/7-10/5
=10/2
=5/1
脱式计算 (4/1减10/1)乘以40
(1/4-1/10)×40
=1/4*40-1/10*40
=10-4
=6
23/2*9/10+27/2除以10/9脱式计算
23/2*9/10+27/2除以10/9
=23/2*9/10+27/2*9/10
=9/10*(23/2+27/2)
=9/10*25
=45/2
10/4 10/1用递等式计算怎么算?
10/4 10/1用递等式计算怎么算?
10分之4+10分之1
=10分之(4+1)
=10分之5
=2分之1

简便计算(17/19)/(10/13)-11/19*13/10
(17/19)/(10/13)-11/19*13/10
=(17/19)*13/10 -11/19*13/10
=(17/19-11/19)*13/10
=6/19*13/10
=39/95
4/5x(10/3+15/4)-8/5脱式计算。
脱式计算
4/5x(10/3+15/4)-8/5
=4/5x10/3+4/5×15/4-8/5
=8/3+3/1-8/5
=24/17-8/5
=12/1
(10/19)除以(3/4)除以(15/38)脱式计算
(10/19)除以(3/4)除以(15/38)
=10/19x4/3x38/15
=40/57x38/15
=16/9
(1)23/13*4/5-4/5*10/13(2)(1/15+2/17)*15*17脱式计算(能简算的要简算)
1)23/13*4/5-4/5*10/13=4/5(23/13-10/13)=4/5
2)(1/15+2/17)*15*17=1/15*15*17++2/17*15*17=17+2*15=47
