Question

Find the decimal number by which the sum of

316.20

and

20.27

exceeds the sum of

130.396

and

120.589

.

Accepted Answer

At first, we will find the sum of $316.20$ and $20.27$ , then find the sum of $130.396$ and $120.589$ , and hence, find the difference between these two sums to find the required decimal number.

Now, to find $316.20 + 20.27$

$\begin{matrix} 3 & 1 & 6 & . & 2 0 \\ + & 2 & 0 & . & 2 7 \\ 3 & 3 & 6 & . & 4 7 \end{matrix}$

$316.20 + 20.27 = 336.47$

Now, to find $130.396 + 120.589$

$\begin{matrix} 1 & 3 & 0 & . & 3 9 6 \\ + & 1 & 2 & 0 & . & 5 8 9 \\ 2 & 5 & 0 & . & 9 8 5 \end{matrix}$

$130.396 + 120.589 = 250.985$

Finally, to find $336.47 - 250.985$

$\begin{matrix} 3 & 3 & 6 & . & 4 7 0 \\ - & 2 & 5 & 0 & . & 9 8 5 \\ 8 & 5 & . & 4 8 5 \end{matrix}$

$336.47 - 250.985 = 85.485$

Therefore, the required decimal number $= 85.485$

Find the decimal number by which the sum of $316.20$ and $20.27$ exceeds the sum of $130.396$ and $120.589$ .
