Question

# What is the level of precision for the solution to the addition problem below? Given: The numbers are 6.339m, 0.170m and 30.4m and the operation is addition.

Decimals
Calculation Find the sum of given three numbers. $$\displaystyle{6.339}{m}+{0.170}{m}+{30.4}{m}={36.909}{m}$$ The sum of three numbers 6.339m, 0.170m and 30.4m is 36.909m. If we add first option 0.001m to 36.909m then the answer would be 36.91m. It can be seen that the number converted from three decimals to two two decimals it can be precison of measurement. Let's check the further options. Add second option 0.01m to 36.909m then the answer would be 36.919m. It can be seen that the number is still of three decimals. Add third option 0.1m to 36.909m then the answer would be 37.009m. It can be seen that the number is still of three decimals. Add fourth option 1m to 36.909m then the answer would be 37.909m. It can be seen that the number is still of three decimals. Therfore, the level of precision is 0.001m. Answer: Therfore, the level of precision is 0.001m.
