P&aacute;g. 1
1 Realiza las sumas siguientes:
a) 6 h 15 min 30 s + 1 h 18 min 45 s
b) 2 h 37 min 12 s + 43 min 18 s
c) 3 h 24 min 16 s + 1 h 50 min 58 s
a) 7 h 34 min 15 s
b) 2 h 80 min 30 s = 3 h 20 min 30 s
c) 4 h 74 min 74 s = 5 h 15 min 14 s
2 Calcula estas sumas de &aacute;ngulos:
a) 12&deg; 16' 37'' + 15&deg; 42' 35''
b) 84&deg; 25' 52'' + 12&deg; 46' 33''
a) 27&deg; 58' 72'' = 27&deg; 59' 12''
b) 96&deg; 71' 85'' = 97&deg; 12' 25''
3 Realiza las siguientes restas:
a) 3 h 38 min 28 s – 46 min 12 s
b) 2 h 23 min 13 s – 1 h 42 min 20 s
c) 2 h – 1 h 16 min 30 s
a) 2 h 98 min 28 s – 46 min 12 s = 2 h 52 min 16 s
b) 1 h 82 min 73 s – 1 h 42 min 20 s = 40 min 53 s
c) 1 h 59 min 60 s – 1 h 16 min 30 s = 43 min 30 s
4 Calcula estas diferencias de &aacute;ngulos:
a) 85&deg; 45' – 18&deg; 37' 19''
b) 70&deg; 49' 12'' – 36&deg; 57' 10''
c) 62&deg; 14' 21'' – 18&deg; 27' 35''
a) 85&deg; 45' – 18&deg; 37' 19'' = 85&deg; 44' 60'' – 18&deg; 37' 19'' = 67&deg; 7' 41''
b) 70&deg; 49' 12'' – 36&deg; 57' 10'' = 69&deg; 109' 12'' – 36&deg; 57' 10'' = 33&deg; 52' 2''
c) 62&deg; 14' 21'' – 18&deg; 27' 35'' = 61&deg; 73' 81'' – 18&deg; 27' 35'' = 43&deg; 46' 46''
^
^
5 Dados estos &aacute;ngulos: A = 88&deg; 15'
^
^
se pide: a) A + B
^
^
^
^
^
^
^
^
^
^
^
^
b) A – B
B = 46&deg; 29' 35''
^
^
^
c) A + B + C
^
^
C = 12&deg; 50' 18''
^
^
d) A – B – C
a) A + B = 88&deg; 15' + 46&deg; 29' 35'' = 134&deg; 44' 35''
b) A – B = 88&deg; 15' – 46&deg; 29' 35'' = 87&deg; 74' 60'' – 46&deg; 29' 35'' = 41&deg; 45' 25''
c) A + B + C = 88&deg; 15' + 46&deg; 29' 35'' + 12&deg; 50' 18'' = 146&deg; 94' 53'' = 147&deg; 34' 53''
d) A – B – C = 88&deg; 15' – 46&deg; 29' 35'' – 12&deg; 50' 18'' = 40&deg; 105' 25'' – 12&deg; 50' 18'' = 28&deg; 55' 7''
6 Calcula.
a) (52 min 13 s) &middot; 10
b) (1&deg; 16' 15'') &middot; 4
a) (52 min 13 s) &middot; 10 = 520 min 130 s = 522 min 10 s = 8 h 42 min 10 s
b) (1&deg; 16' 15'') &middot; 4 = 4&deg; 64' 60'' = 5&deg; 5'

7 Calcula la medida de los &aacute;ngulos cuya amplitud sea el doble y el triple, respectiva^
mente, de la del &aacute;ngulo M = 22&deg; 25' 43''.
^
• 2M = 2 &middot; (22&deg; 25' 43'') = 44&deg; 50' 86'' = 44&deg; 51' 26''
^
• 3M = 3 &middot; (22&deg; 25' 43'') = 66&deg; 75' 129'' = 67&deg; 17' 9''
8 Divide.
a) 109&deg; : 4
b) 21&deg; 40' : 5
c) 101&deg; 38' 24'' : 21
d) 166&deg; 17' 48'' : 28
a) 109&deg; : 4 = 27&deg; 15'
b) 21&deg; 40' : 5 = 4&deg; 20'
c) 101&deg; 38' 24'' : 21 = 4&deg; 50' 24''
d) 166&deg; 17' 48'' : 28 = 5&deg; 56' 21''
9 Si divides una hora en 25 intervalos iguales, &iquest;cu&aacute;nto dura cada intervalo?
60 min 25
– 50 min 2 min
