Question

Of the trees in Keller Forest, 50% are spruce, one-tenth are maple, three-twentieths are pine, and 25% are oak. What fraction, decimal, and percent, represent the amount of pine and spruce trees?

Answer 1

sorry, but your percentages add up to more than 100%
pine+spruce = 3/12 + 1/2 = 3/4 = 75%
