0.015 Km = 1.5×___m=1.5×___dm=1.5×___cm=1.5×___mm
12.5 mm =1.25×___m=1.25×___Km
10 nm =1.0×___cm =1.0×___m
2.5 h = ___min =___s
120 s =___min ___h
12.5 mm =1.25×___m=1.25×___Km
10 nm =1.0×___cm =1.0×___m
2.5 h = ___min =___s
120 s =___min ___h
晕，这答案可不能就这样随便的给了，这是很简单的题目呀，自己好好看书。考试的时候你也能这样问别人吗？
0.015 Km = 1.5×_10__m=1.5×__100_dm=1.5×_1000__cm=1.5×__10000_mm
12.5 mm =1.25×_0.001__m=1.25×_0.00000__Km
10 nm =1.0×_0.00000001cm =1.0×_000000001_m
2.5 h = __150_min =__9000_s
120 s =__2_min _1/30__h
0.015 Km = 1.5×10m=1.5×100dm=1.5×1000cm=1.5×10000mm
12.5 mm =1.25×10^-2m=1.25×10^-5Km
10 nm =1.0×10^-6cm =1.0×10^-8m
2.5 h = 150min =9000s
120 s =2min =0.0333h
