If 1/10 of 1 percent of the population gets a flu vaccine what will the ratio of people treated be?

To determine the ratio of people treated with a flu vaccine, we need to understand the given information first:

The information provided states that 1/10 of 1 percent of the population receives a flu vaccine.

First, let's convert the "1/10 of 1 percent" into a decimal.
1/10 percent is equivalent to 0.1/100, which simplifies to 0.001.

The ratio can be calculated by dividing the number of people treated with the flu vaccine by the total population.

Let's assume the total population is N.

Based on the information given, the number of people treated with the flu vaccine is 0.001 times the total population (0.001 * N).

Therefore, the ratio of people treated is (0.001 * N) / N, which simplifies to 0.001.

So, the ratio of people treated with a flu vaccine is 0.001.
