Question

Place parentheses, if needed, to make the following equations true.

Answer 1

Given:

`4+3.3=21`

To make the equation true, we need to place parentheses at the right place in the equation.

Hence, the equation is;

`\begin{gathered} (4+3).3=21 \\ Solvi\text{ng the parentheses first,} \\ 7.3=21 \\ 7*3=21 \\ 21=21 \\ \\ \text{Hence, this is TRUE.} \end{gathered}`

Therefore, the correct answer to make the equation true is;

`(4+3).3=21`

Hence, OPTION A is correct.
