Answer 1

We can calculate the number of people suffering malnutrition in the world by using the Rule of three:

If 200 is the total population, then 28 suffer from malnutrition.

Then, if the total population is 6.9 billion people, x suffer from malnutrition:

`\begin{gathered} 200\longrightarrow28 \\ 6.9\longrightarrow x=6.9\cdot(28)/(200)=6.9\cdot0.14=0.966\approx0.97 \end{gathered}`

Answer: The number of people of the world's population that suffer from malnutrition is 0.97 billion.
