Answer 1

Stim ca 1°=60'

Ce depaseste 60' se trece la grade, spre exemplu daca avem 3°75'=4°15'

a)

25°+73°=98°

13°12'+47°35'=60°47'

103°44'+67°39'=171°23'

b)

73° -25°=48°

35°43' -17°35'=18°8'

28°15' -19°42'=27°75'-19°42'=8°33'

103° -25°13'=102°60'-25°13'=75°47'

c)

27° -3°=24°

32°14'-4°=28°4'

18°32'-5°=13°32'

d)

144°:6=24°

32°:5=30°120':5=6°24'

25°15': 3​=24°75':3=8°25'
