Question

Which of the following statements demonstrates the identity property of addition?

• A. $(2+5)+7=2+(5+7)$
• B. $\frac{2}{3}+\frac{-2}{3}=0$
• C. $\frac{2}{3}+0=\frac{2}{3}$
• D. $3+5=5+3$

Answer 1

The correct option is C $\frac{2}{3}+0=\frac{2}{3}$

The identity property of addition states that there is a number 0, called the additive identity, that can be added by any number to obtain that number.

Of the four statements, $\frac{2}{3}+0=\frac{2}{3}$ demonstrates this property.
