Дз на вторник, на 24 марта 2026 г (5 кл.). 1. Вычислите: а) 2/9 + 4/9 6) 3 1/4 + 5 34 в) 10 5/6 г) 32 6/11 4 7/11 д) (34,09 + 0,346 5,1) * 1000 e) 288: 1,8

а) \(\frac{2}{9} + \frac{4}{9} = \frac{2+4}{9} = \frac{6}{9} = \frac{2}{3}\)

б) \(3 \frac{1}{4} + 5 \frac{3}{4} = 3 + \frac{1}{4} + 5 + \frac{3}{4} = 8 + \frac{1+3}{4} = 8 + \frac{4}{4} = 8 + 1 = 9\)

в) \(10 - \frac{5}{6} = \frac{10 \cdot 6}{6} - \frac{5}{6} = \frac{60}{6} - \frac{5}{6} = \frac{60-5}{6} = \frac{55}{6} = 9 \frac{1}{6}\)

г) \(32 \frac{6}{11} - 4 \frac{7}{11} = 32 + \frac{6}{11} - 4 - \frac{7}{11} = 28 - \frac{1}{11} = 27 \frac{11}{11} - \frac{1}{11} = 27 \frac{10}{11}\)

д) \((34.09 + 0.346 - 5.1) \times 1000 = (34.436 - 5.1) \times 1000 = 29.336 \times 1000 = 29336\)

е) \(288 : 1.8 = 2880 : 18 = 160\)
