There are about 400 cocoa beans in a pound. There are 2.2 pounds in a kilogram. About how many grams does a cocoa bean weigh?

Question

Hi! My name is Sean, I don't understand this problem and I'm looking for some help. Thanks.

Answer 1

Use dimensional analysis (unit factor) as follows:

400 beans/lb x 2.2 lbs/kg x 1 kg/1000 g = 880 g for the 400 beans

880 g/400 beans = 2.2 g per bean
