# Find the sum of $0.007+8.5+30.08$.

Hint: Summation of all three numbers can be given as, $Total=a+b+c$ . For example, summation of three number i.e. 0.1, 0.2, 0.3 is given as $Total=\ 0.1+0.2\ +0.3=0.6$ . Now, using this same concept we will solve the problem and find our answer.
\begin{align} & \text{ }0.007 \\ & +8.500 \\ & \overline{\text{ }8.507} \\ \end{align}
Here, the answer we got is in three decimal places,Summation of all three numbers can be given as, $Total=a+b+c$ . So, now we will write 30.08 as 30.080 i.e. up to three decimal places. So, on adding we get as
\begin{align} & \text{ 8}.507 \\ & +30.080 \\ & \overline{\text{ 3}8.587} \\ \end{align}
Thus, the sum of $0.007+8.5+30.08$ is 38.587.
