Hello, the answer of each option is given below.
- [tex]\frac{2}{7}+\frac{1}{7}+\frac{1}{7}=\frac{4}{7}[/tex]
- [tex]\frac{4}{8}-\frac{3}{10}=\frac{(10.4)-(8.3)}{(8.10)}=\frac{16}{80}=\frac{16/16}{80/16}=\frac{1}{5}[/tex]
- [tex]3.5+12.11+105.007=120.617[/tex]
- Missed equation that's why we can not solve effectively.
- [tex]652.835-321.6571=331.1779[/tex]
Good luck! These are four-operation-equations. We should calculate by our hand or try to use calculator to get the result. Anyway, If you have any question(s), then feel free to ask in comments!
