Краткое пояснение: Решаем примеры на сложение смешанных чисел и обыкновенных дробей. Приводим дроби к общему знаменателю, выделяем целую часть из неправильных дробей.
-
\(\frac{7}{3}+4 = \frac{7}{3} + \frac{4 \cdot 3}{3} = \frac{7}{3} + \frac{12}{3} = \frac{7+12}{3} = \frac{19}{3} = 6\frac{1}{3}\)
-
\(5+2\frac{3}{14} = 7\frac{3}{14}\)
-
\(8\frac{10}{51}+\frac{7}{51} = 8 + \frac{10}{51} + \frac{7}{51} = 8 + \frac{10+7}{51} = 8 + \frac{17}{51} = 8\frac{17}{51}\)
-
\(8+\frac{1}{5} = 8\frac{1}{5}\)
-
\(\frac{13}{18}+\frac{17}{18} = \frac{13+17}{18} = \frac{30}{18} = \frac{5}{3} = 1\frac{2}{3}\)
-
\(5\frac{4}{15}+13 = 18\frac{4}{15}\)
-
\(\frac{13}{24}+11\frac{3}{24} = 11 + \frac{13}{24} + \frac{3}{24} = 11 + \frac{13+3}{24} = 11 + \frac{16}{24} = 11\frac{2}{3}\)
-
\(9\frac{5}{9}+\frac{1}{9} = 9 + \frac{5}{9} + \frac{1}{9} = 9 + \frac{5+1}{9} = 9 + \frac{6}{9} = 9\frac{2}{3}\)
-
\(7+21\frac{15}{16} = 28\frac{15}{16}\)
-
\(7\frac{3}{19}+\frac{16}{19} = 7 + \frac{3}{19} + \frac{16}{19} = 7 + \frac{3+16}{19} = 7 + \frac{19}{19} = 7 + 1 = 8\)
-
\(1\frac{2}{3}+\frac{2}{3} = 1 + \frac{2}{3} + \frac{2}{3} = 1 + \frac{2+2}{3} = 1 + \frac{4}{3} = 1 + 1\frac{1}{3} = 2\frac{1}{3}\)
-
\(\frac{21}{32}+\frac{19}{32} = \frac{21+19}{32} = \frac{40}{32} = \frac{5}{4} = 1\frac{1}{4}\)
-
\(\frac{27}{28}+4\frac{9}{28} = 4 + \frac{27}{28} + \frac{9}{28} = 4 + \frac{27+9}{28} = 4 + \frac{36}{28} = 4 + \frac{9}{7} = 4 + 1\frac{2}{7} = 5\frac{2}{7}\)
