To find the fraction of the fliers that Rosalia gave out on Wednesday, we first need to determine the total number of fliers she distributed over the three days. We can calculate this as follows:
- Fliers given out on Monday: 85
- Fliers given out on Tuesday: 66
- Fliers given out on Wednesday: 99
Now, let's find the total number of fliers given out:
\[ \text{Total fliers} = 85 + 66 + 99 \]
Calculating the total:
\[ 85 + 66 = 151 \] \[ 151 + 99 = 250 \]
So, the total number of fliers is 250.
Next, we want to determine what fraction of these fliers were given out on Wednesday. The number of fliers given out on Wednesday is 99. Therefore, the fraction of the total fliers given out on Wednesday is:
\[ \text{Fraction} = \frac{\text{Fliers on Wednesday}}{\text{Total fliers}} = \frac{99}{250} \]
Now, let's present the answer using a diagonal fraction bar:
\[ \frac{99}{250} \]
In conclusion, Rosalia gave out \(\frac{99}{250}\) of the fliers on Wednesday. The process involved summing the fliers distributed over three days to find the total and then forming the fraction of the fliers given out specifically on Wednesday.
