Question

Вычислите (19 1/4 - 18 5/8) + (27 - 26 13/24)

Answer 1

1) $19\frac{1}{4} - 18\frac{5}{8} = 1\frac{2 - 5}{8} = \frac{8}{8} - \frac{3}{8} = \frac{5}{8}$

2) $27 - 26\frac{13}{24} = 26\frac{24}{24} - 26\frac{13}{24} = \frac{11}{24}$

3) $\frac{5}{8} + \frac{11}{24} = \frac{26}{24} = 1\frac{2}{24} = 1\frac{1}{12}$
