Question

выполни действия: 11/18+5/12;5/3-3/7;5/6-3/9-1/15​

Answer 1

1) $\frac{11}{18} + \frac{5}{12} = \frac{22}{36} + \frac{15}{36} = \frac{37}{36} = 1\frac{1}{36}$

2) $\frac{5}{3} - \frac{3}{7} = \frac{35}{21} - \frac{9}{21} = \frac{26}{21} = 1\frac{5}{21}$

3) $\frac{5}{6} - \frac{3}{9} - \frac{1}{15} = \frac{75}{90} - \frac{30}{90} - \frac{6}{90} = \frac{39}{90}$
