Question

What is to be added to $65.7$ to get $100$?

Answer 1

Let ‘ x ’ be the number

Now we can write it as let us verify:

$$\begin{gathered} \Rightarrow 65.7+x=100 \\ \Rightarrow x=100-65.7 \\ Atfirst,weconvertthegivendecimalstolikedecimalsas100.0-65.7 \\ Writingthesedecimalsinacolumnformbyaligningdecimalpoints,weget \\ 100.0 \\ -65.7 \\ \_\_\_\_\_\_ \\ 34.3 \\ \_\_\_\_\_\_ \\ So,x=34.3 \end{gathered}$$

Therefore, $34.3$ is to be added to $65.7$ to get $100$.
