which of these expressions are equivalent to p/3?

Question

which expression are equivalent to p/3?

A. p-2/3

B. 1/3p

C. p-3

D. 3/p

E. 3p/p

F. 1/3p+1/3p+1/3p

Answer 1

We can read p/3 as (1/3)p.   If we ignore the p variable, and focus on the coefficient 1/3, we pick the expression that has coefficients that add up to or has a difference of 1/3.

 

Choice A   has   1 - (2/3) = (3 / 3) - (2 / 3) = 1 / 3

 

Choice B also has the coefficient of 1/3. 

 

 

One of these choices is the correct one.  But unless I am interpreting the expressions correctly, I cannot tell you an accurate answer.   Please use parenthesis to make your expressions clearer next time you post these questions.
