dm3.分析:(1)把0.6米换算成厘米数,用0.6乘进率100得60厘米;
(2)把4.2分米2换算成米2数,用4.2除以进率100得0.042米2;
(3)把0.25升换算成毫升数,用0.25乘进率1000得250毫升;
(4)把2.75m3换算成dm3数,用2.75乘进率1000得2750dm3.
(2)把4.2分米2换算成米2数,用4.2除以进率100得0.042米2;
(3)把0.25升换算成毫升数,用0.25乘进率1000得250毫升;
(4)把2.75m3换算成dm3数,用2.75乘进率1000得2750dm3.
解答:解:(1)0.6米=60厘米;
(2)4.2分米2=0.042米2;
(3)0.25升=250毫升;
(4)2.75m3=2750dm3.
故答案为:60,0.042,250,2750.
(2)4.2分米2=0.042米2;
(3)0.25升=250毫升;
(4)2.75m3=2750dm3.
故答案为:60,0.042,250,2750.
点评:此题考查名数的换算,把高级单位的名数换算成低级单位的名数,就乘单位间的进率;把低级单位的名数换算成高级单位的名数,就除以单位间的进率.
