Hi all,
I'm trying to simplify t = [tex]\frac{(3b * 4)}{2b}[\MATH]
In my head it simplifies to 3b*2, but the answer is 6?
Thx,

Use the [Tex] tags; Latex hasn't been working for a while.
$\displaystyle \frac{3b\times~4}{2b}$
Writing '4' as 2x2, we have:
$\displaystyle =\frac{3\times b\times 2\times 2}{2\times b}$
Just rearranged slightly for clarity:
$\displaystyle =\frac{2\times b\times 2 \times 3}{2 \times b}$
Just cancel like terms from here.
$\displaystyle =6$
Where did you go wrong, exactly?
