A package of flour holds 2/7 of a kilogram. How many packages do I need to package 8 kg of flour?

To find out how many packages are needed to package 8 kg of flour, we first need to find out how many packages are needed for 1 kg of flour.

Given: 1 package = 2/7 kg of flour

We want to find, how many packages for 1 kg of flour. Let's call this as x.

x \cdot \left(\dfrac{2}{7}\, \text{kg}\right) = 1\, \text{kg}

Solving for x:

x = \dfrac{1}{\left(\dfrac{2}{7}\right)} = \dfrac{7}{2}

So, 1 kg of flour requires \dfrac{7}{2} packages.

To package 8 kg of flour, we multiply the number of packages for 1 kg of flour by 8:

8 \, \text{kg} \cdot \left(\dfrac{7}{2} \, \text{packages}\right) = 28 \, \text{packages}

Therefore, you would need 28 packages to package 8 kg of flour.

Answer: 28 packages
