23乘33分之32简便计算
23乘33分之32 简便计算 -
33分之32=(1-33分之1) 所以=23乘(1-33分之1)运用乘法分配律=23乘1-23乘33分之1=23-33分之23=22又33分之10
=23/33×(33-1)=23/33×33-23/33×1 =23-23/33 =22又10/33
33分之32=(1-33分之1) 所以=23乘(1-33分之1)运用乘法分配律=23乘1-23乘33分之1=23-33分之23=22又33分之10
=23/33×(33-1)=23/33×33-23/33×1 =23-23/33 =22又10/33
=32-32/33 =31又33分之1

32/33×34用简便方法计算:32/33×34 =32/33×(33+1)32/33×33+32/33×1 =32+32/33 =32又32/33
直接算,
33分之32乘32简便计算 -
32/33×32 =(1-1/33)×32 =32-32/33 =31又1/33
33分之32×34 =32/33x(33+1)=32/33x33+32/33 =32+32/33 =32又32/33
32/33×32简便计算,谢谢 -
32/33*32 =(33-1)*32/33 =33*32/33-32/33 =32-32/33 =31又1/33
32/33*34 =32/33*(33+1)32+32/33 =32又32/33
