Jeanine bought 18 pencils and Clare bought half as many pencils. If Jeanine gave one third of his pencils to Abby, how many more pencils than Clare does Jeanine have now? Let's be accurate as possible.
Clare bought half of 18 pencils which is 18 / 2 = 9 pencils. One - third of 18 pencils is (1 / 3) * 18 = 6 pencils. Jeanine gave out 6 pencils so he has 18 - 6 = 12 pencils left. Jeanine now has 12 - 9 = 3 pencils.
The answer: 3.
