A board that is 12 feet long must be cut into 2 pieces that have lengths in a ratio of 3 to 2. Find the lengths of the two pieces.

Let x = the longer piece.
3/5 = x/12
5x = 36
x = 7.2
12  7.2 = ? 
variable L= length
and we have 12:2 is = 6
and then the ratio 2/3
is 2/3 L=9
check:
129=3 If they asking continues answer will be 3
so both sides are make sense
6=2/3(9) check from the 12 feet long we have 12= L+3= 12=12
if this helpful
6= 6
