i am confuse
X:3?????????????
Is this X=3, OR X/3
: This symbol some thine call ratio or sometime use for division or some time for equal sign
3/(x/9) = 3*(9/x) = 27/x
so, now you have
27/x = 27/5
x = 5
Sorry Khan, I was trying to say that I needed to solve for x in the problem: 3 divided by x over 9 = 5 and two fifths.
.
Steve, thanks for the answer. But, I'm still not sure how you solved for x after getting 27/x= 27/5. Did you multiply both sides by 1/27 to get x by itself?
