Is 1/3 equivalent to 1/3x explain your reasoning
Answers
So the question is does 1/3 = 1/3x
To solve this, basically we just have to solve for x to see if it gives us a true statement. Since x is a variable, it could represent any number... so we have to determine whether the statement could be true with any other numbers as well...
1/3 = 1/3x divide each side by 1/3 (multiply by the reciprocal) 1/3 x 3/1 = x 1 = x
So when x = 1 then the statement 1/3 = 1/3x is true. If we put any other number as x the statement would be false... for example if you let x = 2, then 1/3 x 2/1 = 2/3... that does not equal 1/3 so it is a false statement and they are not equivalent when x = 2.
Your answer is, YES 1/3 is equivalent to 1/3x but ONLY when x = 1
