Katoni bought 2 1/2 dozen of pencils, there are 12 in a dozen how many pencils did katoni buy?

She bought 30pencils 2 dozens are 24 together a half is 6 and 24+6 is 30

First you have to do 12 x 2 because katoni bought 2 dozens of pencils and there are 12 in each. That equals 24. Half a dozen is 6 because you do 12/6. Then you add 24 and 6 which equals 30. So Katoni bought 30 pencils
