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

Answer 1

400 beans/lb = 400 beans/454 g

= 1.14 g/bean

Work:

400 beans/1 pound

=

1 bean/x pounds

400x = 1

x = 1/400

x = .0025

1 bean = .0025 pounds

2.2 pounds/1 kg

=

.0025 pounds/x kg

2.2x = .0025

x = .0025/2.2

x = 0.0011363636363636363636363636363636

1 bean = .0011 kg

0.0011363636363636363636363636363636 * 1000 = 1.1363

~1.14 g/bean!

Answer 2

1.14

Work: 400 beans * 2.2 = 880 then 1000/880

Answer 3

There are 400 beans in a pound, and 2.2 pounds in a kilogram, so 400 x 2.2 = 880 beans in a kilogram. 1000/880 = approx. 1.36 grams per bean
