Question

Rewrite the equation with one set of parentheses to make it true. 20 + 10 ÷ 7 - 2 = 22

Answer 1

Let's begin by identifying key information given to us:

`\begin{gathered} 20+10/7-2=22​ \\ 20+10/(7-2)=22​ \\ \Rightarrow20+10/5=20+(10)/(5) \\ \Rightarrow20+2=22 \\ \\ \\ \\ \therefore20+10/(7-2)=22 \end{gathered}`

Therefore, the rewritten equation is:

20 + 10\(7 - 2) = 22
