Convert them to comparable thingummys
convert to fraction
percent means parts out of 100
30%=30/100=3/10
3/10 vvs 1/3
make bottom number 30
3/10 times 3/3=9/30
1/3 times 10/10=10/30
10/30>9/30
1/3 is bigger
A = first piece, b = second piece, c = third piece
a + b + c = 47
b = 3a
c = 5a + 2
a + (3a) + (5a + 2) = 47.....combine like terms
9a + 2 = 47
9a = 47 - 2
9a = 45
a = 45/9
a = 5 ft
b = 3a.....b = 3(5)....b = 15 ft
c = 5a + 2....c = 5(5) + 2.....c = 25 + 2....c = 27 ft
longest piece (c) = 27 ft
