Oblicz:

a) (¹¹₁₈ + ³₈) - ( ⁷₂₄ +⁴₉)=

b) (7 ⁵₁₈ + 2 ¹¹₂₄) - ( 3 ⁵₈ + 2 ⁸₉)=

c) ( 6 ¹¹₁₈ + 3 ³₄) - ( 10 ⁷₉ - 5 ¹¹₁₂)=

d) (37 ¹₂ - 3 ³₈) - ( 7 ⁵₆ + 8 ³₄ ) + ( 15 ²₃ - 9 ⁵₈ ) =

e) ( 36 ⁴₅ - 12 ³₁₀ - 4 ²₁₅) - ( 1 ¹₃₀ + 8 ¹¹₂₀) - ( 5 ³₈ + ³₁₆ + 3 ¹₄₈)=

Z góry dziękuję i możecie pisać w skrótach. A i te np. 2 ¹₂ lub 67 ⁴⁴₅₃ to są ułamki-po prostu, ja tak piszę ;DDD.

postarajcie się wysłać w sobotę ;**

krysta $a) \\(\frac{11}{8} + \frac{3}{8}) - (\frac{7}{24} +\frac{4}{9})= (\frac{11}{8} + \frac{3}{8}) - (\frac{7}{24} +\frac{4}{9})=\frac{14}{8} -(\frac{63}{216} +\frac{96}{216}) = \frac{378}{216} -\frac{159}{216} =\frac{219}{216}=\frac{73}{72}=1\frac{1}{72}$

$b)\\ (7\frac{ 5}{18} + 2 \frac{11}{24}) - ( 3\frac{5}{8} + 2\frac{8}{9})=(7\frac{20}{72} + 2 \frac{33}{72}) - ( 3\frac{45}{72} + 2\frac{64}{72})=\\ \\9\frac{53}{72} - 5\frac{109}{72} =9\frac{53}{72} -6\frac{37}{72} = 3\frac{16}{72}=3\frac{2}{9}$

$c) \\( 6 \frac{11}{18} + 3 \frac{3}{4}) - ( 10\frac{ 7 }{9} - 5 \frac{11}{12})=( 6 \frac{22}{36} + 3 \frac{27}{36}) - ( 10\frac{ 84 }{108} - 5 \frac{99}{108})=\\ \\9\frac{49}{36}-4\frac{93}{108}=9\frac{147}{108}-4\frac{93}{108}=5\frac{54}{108}=5\frac{1}{2}$

$d)\\ (37 \frac{1}{2} - 3\frac{3}{8}) - ( 7 \frac{5}{6}+ 8\frac{3}{4} ) + ( 15 \frac{2}{3} - 9 \frac{5}{8} ) =\\ \\(37 \frac{4}{8} - 3\frac{3}{8}) - ( 7 \frac{10}{12}+ 8\frac{9}{12} ) + ( 15 \frac{16}{24}-9 \frac{15}{24} ) =\\ \\34 \frac{1}{8}-15\frac{19}{12}+6\frac{1}{24}=34 \frac{1}{8}-16\frac{7}{12}+6\frac{1}{24}=$

$34 \frac{1}{8}-15\frac{19}{12}+6\frac{1}{24}=34 \frac{3}{24}-16\frac{14}{24}+6\frac{1}{24}=\\ \\17\frac{13}{24}+6\frac{1}{24}=23\frac{14}{24}=23\frac{7}{12}$

$e)\\ ( 36\frac{4}{5}- 12 \frac{3}{10} - 4 \frac{2}{15}) - ( 1 \frac{1}{30} + 8\frac{11}{20}) - ( 5 \frac{3}{8} + \frac{3}{16} + 3 \frac{1}{48})=\\ \\( 36\frac{24}{30}- 12 \frac{9}{30} - 4 \frac{4}{30}) - ( 1 \frac{2}{60} + 8\frac{33}{60}) - ( 5 \frac{18}{48} + \frac{9}{48} + 3 \frac{1}{48})=$

$20 \frac{11}{30} - 9\frac{35}{60} - 8 \frac{28}{48}=20 \frac{11}{30} -9\frac{7}{12} - 8 \frac{7}{12}=\\ \\20\frac{22}{60}-9\frac{35}{60} -8 \frac{35}{60}= 2\frac{12}{60}=2\frac{1}{5}$
