Question

dintr-o livada s-au recoltat 23intregi 1/4kg mere si cu17 intregi1/7kg mai multe pere , Cate kg fructe s-au recoltat

Answer 1

$17 \frac{1}{7}= \frac{17*7+1}{7}= \frac{119+1}{7} =\frac{120}{7}$ mere

$23 \frac{1}{4}= \frac{23*4+1}{4}= \frac{93}{4}$

pere:  $\frac{120}{7}+ \frac{93}{4}= \frac{120*4+93*7}{7*4}= \frac{4011}{28}$


mere +pere  $\frac{4011+480}{28} = \frac{4491}{28}$
