Первый ряд:

• \(3\frac{1}{3} + \frac{2}{3} = \frac{10}{3} + \frac{2}{3} = \frac{12}{3} = 4\)
• \(4 + \frac{1}{2} = \frac{8}{2} + \frac{1}{2} = \frac{9}{2} = 4\frac{1}{2}\)
• \(4\frac{1}{2} + \frac{1}{4} = \frac{18}{4} + \frac{1}{4} = \frac{19}{4} = 4\frac{3}{4}\)

Второй ряд:

• \(\frac{2}{5} + \frac{1}{3} = \frac{6}{15} + \frac{5}{15} = \frac{11}{15}\)
• \(\frac{11}{15} + 5 = \frac{11}{15} + \frac{75}{15} = \frac{86}{15} = 5\frac{11}{15}\)
• \(5\frac{11}{15} + 3\frac{1}{3} = 5\frac{11}{15} + 3\frac{5}{15} = 8\frac{16}{15} = 9\frac{1}{15}\)

Третий ряд:

• \(\frac{3}{5} - \frac{1}{2} = \frac{6}{10} - \frac{5}{10} = \frac{1}{10}\)
• \(\frac{1}{10} + \frac{4}{7} = \frac{7}{70} + \frac{40}{70} = \frac{47}{70}\)
• \(\frac{47}{70} - \frac{2}{3} = \frac{141}{210} - \frac{140}{210} = \frac{1}{210}\)

Четвертый ряд:

• \(3\frac{2}{5} - 2\frac{3}{4} = \frac{17}{5} - \frac{11}{4} = \frac{68}{20} - \frac{55}{20} = \frac{13}{20}\)
• \(\frac{13}{20} + \frac{3}{7} = \frac{91}{140} + \frac{60}{140} = \frac{151}{140} = 1\frac{11}{140}\)
• \(1\frac{11}{140} - \frac{2}{3} = \frac{151}{140} - \frac{2}{3} = \frac{453}{420} - \frac{280}{420} = \frac{173}{420}\)

Пятый ряд:

• \(5\frac{7}{9} - 2\frac{4}{5} = \frac{52}{9} - \frac{14}{5} = \frac{260}{45} - \frac{126}{45} = \frac{134}{45} = 2\frac{44}{45}\)
• \(2\frac{44}{45} + \frac{3}{4} = \frac{134}{45} + \frac{3}{4} = \frac{536}{180} + \frac{135}{180} = \frac{671}{180} = 3\frac{11}{180}\)
• \(3\frac{11}{180} - \frac{3}{5} = \frac{671}{180} - \frac{3}{5} = \frac{671}{180} - \frac{108}{180} = \frac{563}{180} = 3\frac{23}{180}\)
