Question

Sum of $0.3,0.03$ and $0.003$ is _____

• A. $0.999$
• B. $0.393$
• C. $0.636$
• D. $0.333$

Answer 1

The correct option is D $0.333$

To add $3$ decimal numbers of different decimal values we pick the number with the highest decimal value and expand all the other numbers to the same value by adding $0$ after the decimal point.

$0.300+0.030+0.003=0.333$

So option D is the correct answer!
