Question 2

1. а) $\frac{14}{\frac{1}{2}+\frac{3}{8}} = \frac{14}{\frac{4}{8}+\frac{3}{8}} = \frac{14}{\frac{7}{8}} = \frac{14}{1} * \frac{8}{7} = 16$

б) $\frac{3}{\frac{2}{5}-\frac{1}{3}} = \frac{3}{\frac{6}{15}-\frac{5}{15}} = \frac{3}{\frac{1}{15} } = \frac{3}{1} * \frac{15}{1} = 45$

в) $\frac{12}{1 - \frac{1}{4} } = \frac{12}{\frac{4}{4}-\frac{1}{4} } = \frac{12}{\frac{3}{4} } = \frac{12}{1} * \frac{4}{3} = 16$

2. а) $\frac{1}{1 + \frac{1}{2} } = \frac{1}{\frac{2}{2}+\frac{1}{2} } = \frac{1}{\frac{3}{2} } = \frac{1}{1} * \frac{2}{3} = \frac{2}{3}$

б) $\frac{1}{1 - \frac{2}{3} } = \frac{1}{\frac{3}{3}-\frac{2}{3} } = \frac{1}{\frac{1}{3} } = \frac{1}{1} * \frac{3}{1} = 3$

в) $\frac{1}{1 +\frac{4}{5} } = \frac{1}{\frac{5}{5}+\frac{4}{5} } = \frac{1}{\frac{9}{5} } = \frac{1}{1} * \frac{5}{9} = \frac{5}{9}$

3. а) $\frac{\frac{3}{4}+2 }{1-\frac{3}{4} } = \frac{\frac{3}{4}+1\frac{4}{4} }{\frac{4}{4}-\frac{3}{4} } = \frac{1\frac{7}{4} }{\frac{1}{4} } = \frac{11}{4} * \frac{4}{1} = 11$

б) $\frac{\frac{7}{3}-2 }{1+\frac{7}{3} } = \frac{\frac{7}{3}-1\frac{3}{3} }{\frac{3}{3}+\frac{7}{3} } = \frac{1\frac{4}{3} }{\frac{10}{3} } = \frac{7}{3} * \frac{3}{10} = \frac{7}{10} = 0,7$

в) $\frac{1+\frac{3}{2} }{\frac{3}{2}-1 } = \frac{\frac{2}{2}+\frac{3}{2} }{\frac{3}{2}-\frac{2}{2} } = \frac{\frac{5}{2} }{\frac{1}{2} } = \frac{5}{2} * \frac{2}{1} = 5$

Боже, и такое задают детям? Жесть.
