33分之32×34怎么简便算?
32/33*34=32/33*(1+33)=32+32/33=32又32/33

(32*34)/33=(33-1)(33+1)/33=(33²-1)/33=33-1/33

33分之32×34
=(33-1)(33+1)/33
=33-1/33
=32又32/33

原式=(33-1)*(33+1)/33=(33^2-1)/33=33^2/33-1/33=33-1/33=32又32/33.希望你能看懂

32*32/33+1/33 =32*(32/33+1/33)-32/33 =32*1-32/33 =31又32/33 (33+1)乘以33分之32,再加33分之1就行了 34×(32/33+
