Answer:

Gabriela Mistral works as a humanitarian for $8$ days.

Step-by-step explanation:

Gabriela Mistral was a poet, diplomat, teacher and humanitarian such that each week she worked a certain amount of days as a poet diplomat teacher and humanitarian.

Ratio is $1:1:3:2$

Let $x$ denotes total number of days Gabriela Mistral work.

As she works 12 days as a teacher,

$\frac{3}{7}x=12\\ x=\frac{7}{3}(12)\\ x=28$

Total number of days $=x=28$

So,

she works as a humanitarian for $\frac{2}{7}x=\frac{2}{7}(28)=8$ days.
