Bari has 180 Mardi Gras beads. 2/3 of the beads are green. 40% of the remaning beads are gold and the rest are purple. What fraction of the beads are gold? how many purple beads does she have?

2/3 green = 2/3(180) = 120

60 remain

120 + .4(60) + P = 180

Solve for P(urple).

Green=120
Remaining=60
Gold=40% * remaining=40%* 60=24
Purple=36

Fraction of gold=24/180=2/15
