(1)
37°18'+62°56'
相对单位相加
=(37+62)°(18+56)'
=99°74'
根据换算1°=60'
=100°14' (答案(1)🍓🍓🍓)
(2)
179°-72°18'54''
根据换算1°=60'
=178°60'-72°18'54''
根据换算1'=60''
=178°59'60''-72°18'54''
相对单位相减
=(178-72)°(59-18)'(60-54)''
=106°41'8'' (答案(2)🍓🍓🍓)
(3)
31°16'×5
相对单位相乘
=(31x5)°(16x5)'
=155°80'
根据换算1°=60'
=156°20' (答案(3)🍓🍓🍓)
(4)
15°20'÷5
相对单位相除
=(15÷5)°(20÷5)'
=3°4' (答案(4)🍓🍓🍓)
37°18' + 62°56' = 100°14'
然后,将179°减去72°18'54'',得到:
179° - 72°18'54'' = 106°41'06''
接着,将31°16'乘以5,得到:
31°16' × 5 = 155°80'
因为155°80'可以转化为156°20',所以我们将其表示为:
31°16' × 5 = 156°20'
最后,将15°20'除以5,得到:
15°20' ÷ 5 = 3°4'
因此,37°18'+62°56' 179°-72°18'54'' 31°16'×5 15°20'÷5的结果为:
100°14' + 106°41'06'' + 156°20' + 3°4'
将度、分、秒分别相加,得到:
266°19'10''
=99度74分
=100度14分;
(2)179度一72度18分54秒
=178度59分60秒一72度18分54秒
=106度41分6秒;
(3)31度16分x5
=155度80分
=156度20分;
(4)15度20分÷5
=3度4分。
=99°74'
=100°14'
179°-72°18'54''
=179°59'60''-72°18'54''
=107°41'6''
31°16'×5
=105°80'
=106°20'
15°20'÷5=3°4'
=99°74'
=100°14'
179°-72°18'54''
=179°60'-72°18'54''
=179°59'60''-72°18'54''
=107°41'6''
31°16'×5
=105°80'
=106°20'
15°20'÷5=3°4'
