Question

From the sum of $89.02m$ and $10337cm$, subtract the sum of $832cm$ and $41.58m$.

Answer 1

Step 1: Converting the given values in metres.

$10337cm=\frac{10337}{100}m=10.337m[\because 1cm=\frac{1}{100}m]$,$8.32m$ and $41.58m$

$832cm=\frac{832}{100}m=8.32m[\because 1cm=\frac{1}{100}m]$

Step 2: Calculate the sum of $89.02m$and $103.37m$, and sum of $8.32m$ and $41.58m$.

$$\begin{gathered} 103.37m \\ +89.02m \\ ----- \\ 192.39m \end{gathered}$$

And,

$$\begin{gathered} 41.58m \\ +8.32m \\ ----- \\ 49.90m \end{gathered}$$

Step 3. Subtract $49.90m$ from $192.39m$,

Subtracting the decimals

$$\begin{gathered} 192.39m \\ -49.90m \\ ---- \\ 142.49m \end{gathered}$$

Hence, the required answer is $142.49m$.
