Pls solve this 13th part

Dear Student ,

He gave his property to orphanage = \frac{2}{5} He gave his property to hospital = \frac{1}{7} Let his complete be 1 So, his remaining property will be = 1 - (\frac{2}{5} + \frac{1}{7}) = 1 - (\frac{2 \times 7 + 1 \times 5}{5 \times 7}) = 1 - (\frac{14 + 5}{35}) = 1 - (\frac{19}{35}) = \frac{35 - 19}{35} = \frac{16}{35}

Regards
