Question: There are 18 green leaves on each of the 3 tea leaf plants. One-third of them turn yellow and fall off on each of the tea leaf plants. How many green leaves are left on the tea leaf plants? Think carefully first, then make a decision:
In total, the 3 tea leaf plants have 18 x 3 = 54 green leaves. One - third of the yellow leaves falling off of all plants is 54 / 3 = 18. The number of remaining green leaves on the plants is 54 - 18 = 36. So the answer is 36.
