Question

Which expression represents the word phrase 6 decreased by one-third of a number? a. 6+13−x b. 6+13+x c. 13⋅x−6 d. 6−13⋅x

Answer 1

The answer is D but it is written
$6 - \frac{1}{3} x$
The word decreased means to subtract but as the expression states 1/3 of a number, 6 is subtracted by 1/3 times whatever number X represents.
