分析:(1)化1米=100厘米,先根據(jù)每張紙厚度=總厚度÷紙張數(shù),求出每張紙厚度,再根據(jù)張數(shù)=總厚度÷每張紙厚度即可解答,
(2)根據(jù)總厚度=張數(shù)×每張紙厚度即可解答.
解答:解:(1)1米=100厘米,
100÷(1÷100),
=100÷
,
=10000(張),
答:10000張這樣的紙大約厚1米;
(2)1÷100×100000000,
=0.01×100000000,
=1000000(厘米),
=10(千米),
答:1億張這樣的紙大約厚10千米;
故答案依次為:10000,10.
點評:本題屬于比較簡單應用題,只要依據(jù)數(shù)量間的等量關系,代入數(shù)據(jù)即可解答.
