3/8 + 1/2 =

Привет! Давай решим эти примеры на сложение дробей. Мы будем приводить их к общему знаменателю. 1) $\frac{3}{8} + \frac{1}{2} = \frac{3}{8} + \frac{4}{8} = \frac{7}{8}$ 2) $\frac{3}{8} + \frac{1}{6} = \frac{9}{24} + \frac{4}{24} = \frac{13}{24}$ 3) $\frac{3}{8} + \frac{3}{7} = \frac{21}{56} + \frac{24}{56} = \frac{45}{56}$ 4) $\frac{3}{8} + \frac{3}{16} = \frac{6}{16} + \frac{3}{16} = \frac{9}{16}$ 5) $\frac{3}{8} + 1 \frac{1}{4} = \frac{3}{8} + 1 \frac{2}{8} = 1 \frac{5}{8} = \frac{13}{8}$ 6) $\frac{3}{8} + 2 \frac{5}{8} = 2 \frac{8}{8} = 2 + 1 = 3$ 7) $\frac{3}{8} + \frac{7}{12} = \frac{9}{24} + \frac{14}{24} = \frac{23}{24}$ 8) $\frac{3}{8} + \frac{3}{4} = \frac{3}{8} + \frac{6}{8} = \frac{9}{8} = 1 \frac{1}{8}$ 9) $\frac{3}{8} + \frac{5}{24} = \frac{9}{24} + \frac{5}{24} = \frac{14}{24} = \frac{7}{12}$ 10) $\frac{3}{8} + \frac{5}{6} = \frac{9}{24} + \frac{20}{24} = \frac{29}{24} = 1 \frac{5}{24}$ 11) $\frac{3}{8} + \frac{7}{8} = \frac{10}{8} = \frac{5}{4} = 1 \frac{1}{4}$ 12) $\frac{3}{8} + 1 \frac{1}{4} = \frac{3}{8} + 1 \frac{2}{8} = 1 \frac{5}{8}$ 13) $\frac{3}{8} + \frac{13}{32} = \frac{12}{32} + \frac{13}{32} = \frac{25}{32}$ 14) $\frac{3}{8} + 1 \frac{7}{16} = \frac{6}{16} + 1 \frac{7}{16} = 1 \frac{13}{16}$ 15) $\frac{3}{8} + \frac{11}{72} = \frac{27}{72} + \frac{11}{72} = \frac{38}{72} = \frac{19}{36}$
