3 / 8 = w / w + 2
3 over 8 equals w over w + 2
3 w
_ = _
8 w+2
What is w? My answer is w = 1.2 but I'm not sure.
Yes, that's correct.
$\displaystyle \frac{3}{8}=\frac{w}{w+2}$
Multiply through by $\displaystyle 8(w+2)$:
$\displaystyle 3(w+2)=8w$
$\displaystyle 3w+6=8w$
$\displaystyle 5w=6$
$\displaystyle w=\frac{6}{5}=1.2$
