Тест 10 задание 1
а) $\frac{31}{8}+ \frac{53}{12} = \frac{93+106}{24} = \frac{199}{24} =8 \frac{7}{24}$
б) $\frac{59}{14}+ \frac{65}{21}= \frac{1239+910}{294}= 7\frac{91}{294}$
в) $\frac{34}{17}- \frac{14}{17} = \frac{20}{17} = 1\frac{3}{17}$
г) $4\frac{16}{30} -2 \frac{1}{30} = 2 \frac{15}{30} = 2 \frac{1}{2}$
д) $8 \frac{6}{60}- 3 \frac{10}{60} = 4 \frac{56}{60}$
е) $4- \frac{4}{7} = 3 \frac{3}{7}$
