Bridgette's science class weighed plastic rings for an experiment. They found that the orange ring weighed 1/2 of an ounce, the purple ring weighed 9/10 of an ounce, the white ring weighed 1/10 of an ounce, the yellow ring weighed 4/5 of an ounce, and the red ring weighed 4/5 of an ounce. What was the total weight of the plastic rings?​
