Abby's method and Renato's method of converting kilograms to pounds gives the same answer.

Algebraic expression

  • Number of kilograms = n

Abby:

1/2n - 10%

= 1/2n - 0.1

Renato:

-10% + 1/2n

= -0.1 + 1/2n

Therefore, Abby's method and Renato's method of converting kilograms to pounds gives the same answer.
