(1)2min=__________=____h
(2)2h=__________=____min
2h=__________=____s
(3)30min=__________=____h
30min=__________=____s
(4)45min=__________=____h

(1)2min=2/60h=1/30h
(2)2h=2*60min=120min
2h=2*3600s=7200s
(3)30min=30/60h=0.5h
30min=30*60s=1800s
(4)45min=45/60h=0.75h
(5)120s=120/60min=2min
120s=120/3600h=1/30h
(6)1800s=1800/3600h=0.5h
这种题还要怎么写过程?.

答案是正确的 可过程 不是你这样的

举个例子,如果是长度转换单位的话
2 2 3 5
8.8cm=3.6×10 =3.6×10×10 微米=3.6×10 微米
那跟这差不多的 时间转换单位怎么写

120S,1/30,
120min,120min,
120min,7200s
1800s,0.5h,
0.5h,7200s
