aidica 17x2+7 pentru cei care nu au inteles,

Answer 1

introducerea intregilor in fractie se numeste operatia matematica descrisa


$17 \frac{2}{7}= \frac{17*7+2}{7} = \frac{119+2}{7}= \frac{121}{7} \\ \\ 23 \frac{6}{14}= \frac{23*14+6}{14}= \frac{322+6}{14}= \frac{328}{14} \\ \\ \frac{121}{7} +\frac{328}{14} = \frac{121*2+328}{14}= \frac{242+328}{14} \\ \\ = \frac{570}{14} \\ \\ = \frac{285}{7}$
