Question

A case of tacks weighs 1.29 kilograms. There are 7 boxes in each case, each box having the same weight. How much does each box weigh?

Answer 1

Each box weighs 0.18 kilogram.

Explanation:

We can do proportions to solve.

`(1.29 \: kilograms)/(7 \: boxes) = (x)/(1 \: box) \\ \\ (7x)/(7) = (1.29)/(7) \\ \\ x = 0.18 \\ x = 0.18 \: kilogram`
