Question

甲數(shù)比乙數(shù)多0.1，丙數(shù)比乙數(shù)多0.01，甲數(shù)與丙數(shù)相比

1. A.
   甲數(shù)＞丙數(shù)
2. B.
   甲數(shù)＜丙數(shù)
3. C.
   甲數(shù)=丙數(shù)

Answer 1

A
分析：甲數(shù)比乙數(shù)多0.1，則甲數(shù)=乙數(shù)+0.1；丙數(shù)比乙數(shù)多0.01，即丙數(shù)=乙數(shù)+0.01，因?yàn)?.1＞0.01，所以乙數(shù)+0.1＞乙數(shù)+0.01，即甲數(shù)大于丙數(shù)；據(jù)此選擇即可．
解答：由題意可知：甲數(shù)=乙數(shù)+0.1，丙數(shù)=乙數(shù)+0.01，因?yàn)?.1＞0.01，
所以乙數(shù)+0.1＞乙數(shù)+0.01，即甲數(shù)大于丙數(shù)；
故選：A．
點(diǎn)評(píng)：解答此題的關(guān)鍵：根據(jù)題意，進(jìn)行轉(zhuǎn)化，轉(zhuǎn)化為：甲數(shù)=乙數(shù)+0.1，丙數(shù)=乙數(shù)+0.01，是解答此題的關(guān)鍵．
