Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{1}{3}}}}}} [/tex]
Step-by-step explanation:
[tex] \sf{ \frac{2}{3} + ( - \frac{1}{3} )}[/tex]
We know that [tex] \sf{( + ) \times ( - ) = ( - )}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{2}{3} - \frac{1}{3}} }[/tex]
While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same.
[tex] \dashrightarrow{ \sf{ \frac{2 - 1}{3}}} [/tex]
[tex] \dashrightarrow{ \boxed{ \sf{ \frac{1}{3}}}} [/tex]
Hope I helped!
Best regards! :D
