初一数学上册的 62.125°等于多少，41°18′36″等于多少，20°46′+35°54′等于多少，90°-43′18″等于

Answer 1

62.125°等于62°7′30″，
41°18′36″等于41.31°，
20°46′+35°54′等于56°40′，
90°-43′18″等于89°-16′42″

Answer 2

62.125°=62°7'5''

41°18′36″=41.306°

20°46′+35°54′
=(20°+35°)+(46'+54')
=55°+100'
=55°+1°40'
=56°40'

90°-43'18''
=89°59'60''-43'18''
=89°16'42''

Answer 3

62.125°=62°7.5′=62°7′30″

41°18′36″=41°18.6′=41.31°

20°46′+35°54′=55°100′=56°40′

90°-43′18″=89°59′60″-43′18″=89°16′42″

Answer 4

62.125°=60°7‘30’‘。41°18′36″=41.31°。20°46′+35°54′=56°40’。90°-43′18″=89°16‘42’‘

Answer 5

62.125°等于62°7'20''，41°18′36″等于41.36°，20°46′+35°54′等于56°30'，90°-43′18″等于46°42'

Answer 6

41.306°
