A student translated the phrase below into an algebraic expression, and then evaluated it for g = one-fourth. Is the student’s w
ork correct?
one-third more than the product of four and a number; evaluate when g = one-fourth
The expression is StartFraction 4 Over g EndFraction + one-third; for g = one-fourth. StartFraction 4 Over 1 EndFraction divided by one-fourth + one-third = StartFraction 4 Over 1 EndFraction times StartFraction 4 Over 1 EndFraction + one-third = 16 + one-third = 16 and one-third.
Yes, the student’s work is correct.
No, the student divided the fraction incorrectly
No, the student made an error when substituting.
No, product means multiplication, and the student wrote a division expression.
