Question

Помогите пожаоуйста ответить на г) д) ж) з) е) желательно чтобы решение было фоткой, в тетради

Answer 1

г)
$8 frac{1}{12} - 3 frac{4}{15} - 1 frac{7}{30} = \ = 8 frac{5}{60} - 3 frac{16}{60} - 1 frac{14}{60} = \ = 7 frac{65}{60} - 3 frac{16}{60} - 1 frac{14}{60} = \ = 3 frac{35}{60} = 3 frac{7}{12}$
д)
$(13 - 8 frac{5}{12} ) + (17.5 - 16.2) = \ = 4 frac{7}{12} + 1.3 = \ = 4frac{35}{60} + 1 frac{18}{60} = \ = 5 frac{53}{60}$
ж)
$(15.5 - 2.375) - (5 frac{20}{24} + 6 frac{18}{24} ) + (10 frac{16}{24} - 5 frac{15}{24} ) = \ = 13.125 - 12 frac{2}{3} + 5 frac{1}{24} = \ = 13.125 - 12 frac{16}{24} + 5 frac{1}{24} = \ = 13 frac{125}{1000} - 12 frac{16}{24} + 5 frac{1}{24} = \ = 13 frac{3000}{24000} - 12 frac{16000}{24000} + 5 frac{1000}{24000} = \ = 12 frac{27000}{24000} - 12 frac{16000}{24000} + 5 frac{1000}{24000} = \ = frac{12000}{24000} = frac{1}{2} = 0.5$
з)
$0.25 + 0.75 + (1 frac{36}{24} - frac{17}{24}) = \ = 1 + 1 frac{19}{24} = 2 frac{19}{24}$
е)
$(63 frac{16}{24} + 3 frac{3}{24} ) - 2 frac{4}{9} = \ = 66 frac{19}{24} - 2 frac{4}{9} = \ = 66 frac{57}{72} - 2 frac{32}{72} = \ = 64 frac{25}{72}$
