Which of the following is an example of the identity property of 1 ? \( \begin{array}{l}(0) 7.45=0 \\ 9 \frac{2}{3}(1)=9 \frac{2}{3} \\ -1+2=1 \\ 4 \frac{5}{6}+0=4 \frac{5}{6}\end{array} \)

The identity property of 1 states that any number multiplied by 1 remains unchanged. So in your list, \( 9 \frac{2}{3}(1) = 9 \frac{2}{3} \) perfectly illustrates this property, showing how the number retains its identity when multiplied by 1! On a fun note, this concept isn’t just math chatter! It pops up in various real-life situations. For instance, in the world of identity verification online, proving who you are (like your username) can be as straightforward as “you remain you” when logged in, similar to how numbers stay the same with this property!
