Answer 1

5) 64⁰59'84" - 16⁰34´50´ =  48⁰25´34´
6) 34⁰59'60" -  34⁰0´28´  =  0⁰59'32"
7) 89⁰59'60" -  44⁰0´15´  =  45⁰59'45"
8) 25⁰70'72" -  11⁰30´24´  =  14⁰40'48"

9)  6⁰41'38" x 4  =  24⁰164'152" =  24⁰166'32" = 26⁰46'32"
10) 13⁰41'29" x 3  =  39⁰123'87" =  39⁰124'27" = 41⁰4'27"
11) 35⁰ :2 = 34⁰60' : 2 = 17⁰30'
12) 25⁰12' : 2 = 24⁰72' : 2 = 12⁰36'
