1、1）46.3*0.56+5.38*5.6-1+0.056
=0.56（46.3+53.8+0.1）-1
=0.56*100.2-1
=0.56（100+0.2）-1
=56+0.112-1
=55.112
2）136.24+436.24+736.24+936.24
=36.24+100+36.24+400+36.24+700+36.24+900
=36.24*4+（100+400+700+900）
=144.96+2100
=2244.96
2、答案：C>B>A>D
解析：A+0.6=B-0.6 得出：B>A
C*0.6=D/0.6 得出:C>D
D/0.6=D*(5/3)>(D+D*0.6)=A+0.6 得出：A>D
故：C>B>A>D
3、 答案：这两个数是6.2和6.3.乘积四舍五入前是6.2*6.3=39.06
