texaschic101 · Answer

you could make a proportion and solve

texaschic101 · Answer

6/2 = x/6 -- (6 tala to $2 = x tala to $6)
cross multiply and solve for x

don't feel stupid...believe me, I have asked questions on here and after I found out the answer...I felt the same way....but you shouldn't...we are just learning :)

tkhunny · Answer

And of course, never "cross-multiply"?  There is no reason to multiply by 2 jsut to divide by it again.

$\dfrac{6}{2} = \dfrac{x}{6}$

Simplify the left

$3 = \dfrac{x}{6}$

Multiply by 6

$18 = x$

Done.
