(19/96+1919/96966+191919/969696)÷19191919/96969696今天必须交
(19/96+1919/96966+191919/969696)÷19191919/96969696
今天必须交
(19/96+1919/96966+191919/969696)÷19191919/96969696今天必须交
原式即:
=(1+101/101+10101/10101)*(19/96)÷[(1010101/1010101)*19/96]
=(1+1+1)*(19/96)÷[1*19/96]
=3
(19/96+1919/9696+191919/969696)÷19191919/96969696
=[19/96+(19*101)/(96*101)+(19*10101)/(96*10101)]/[(19*1010101)/(96*1010101)]
=(19/96+19/96+19/96)/(19/96)
=[(3*19)/96]*(96/19)
=3.
题应为
(19/96+1919/9696+191919/969696)÷19191919/96969696
=(19/96+1919/9696+191919/969696)*(96969696/19191919)
=(19/96*(96969696/19191919)+1919/9696*(96969696/19191919)
+191919/969696*(96969696/19191919)
=1+1+1
=3
祝你好运
