Answer:
A. 12%
Explanation:
I counted the number of dots in all, and the number of dots in the columns 7 - 8.
- There are 25 dots in all
- There are 3 dots in columns 7 - 8.
This means that 3/25 of the students in the class have 7 - 8 people in their houses.
Now let's convert the fraction into a decimal, which we'll then convert into a percent.
Let's multiply the numerator and denominator of 3/25 by 4.
We get 12/100!
12/100 as a decimal is 0.12
0.12 as a percent is 12%
Is there a letter which has 12% as an option? Yes, there is! It's A.
The answer is A. 12%
