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. 
   `(2)/(7)+(1)/(7)+(1)/(7)=(4)/(7)`
2. 
   `(4)/(8)-(3)/(10)=((10.4)-(8.3))/((8.10))=(16)/(80)=(16/16)/(80/16)=(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!
