Question

Solve for the indicated operations.

1) 2/7 + 1/7 + 1/7
2) 4/8 - 3/10
3) 3.5 + 12.11 + 105.007
4) 1 275.25 − 97.75 431
5) 652.835 − 321.6571

Answer 1

Hello, the answer of each option is given below.

1. $\frac{2}{7}+\frac{1}{7}+\frac{1}{7}=\frac{4}{7}$
2. $\frac{4}{8}-\frac{3}{10}=\frac{(10.4)-(8.3)}{(8.10)}=\frac{16}{80}=\frac{16/16}{80/16}=\frac{1}{5}$
3. $3.5+12.11+105.007=120.617$
4. Missed equation that's why we can not solve effectively.
5. $652.835-321.6571=331.1779$

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!
