Thomas took a practice test to study for a trivia game show. The circle graph below shows the percentages of topics that were covered on the practice test.
There were 65 questions on the topic of geography on the practice test. What was the total number of questions on the practice test?

No circle graph.
To find the total number of questions on the practice test, we need to determine the percentage of questions represented by the topic of geography.
According to the circle graph, the percentage of questions covered on geography is not given. Please provide the percentage to proceed further.
To find the total number of questions on the practice test, we need to determine the percentage of the test that the topic of geography covers and then use that percentage to calculate the total number of questions.
First, let's look at the circle graph. It shows the percentages of topics covered on the practice test. Since we know that the topic of geography consists of 65 questions, we can find the percentage it represents by dividing the number of questions on geography by the total number of questions and then multiplying by 100.
Let's assume the percentage of the test related to geography is represented by "x."
We can set up an equation:
x/100 = 65/Total number of questions
To solve for the total number of questions, we can cross-multiply:
x = (65/Total number of questions) * 100
Now, we can substitute the known value of x into the equation to find the total number of questions:
65 = (65/Total number of questions) * 100
To isolate the Total number of questions, we divide both sides of the equation by (65/Total number of questions).
Total number of questions = 65 / (65/Total number of questions) * 100
Simplifying further:
Total number of questions = (65 * Total number of questions) / 65 * 100
Now, we can cancel out the 65's on the right side of the equation:
Total number of questions = Total number of questions / 100
Multiplying both sides of the equation by 100 will eliminate the fraction:
100 * Total number of questions = Total number of questions
By subtracting Total number of questions from both sides of the equation:
100 * Total number of questions - Total number of questions = 0
Factoring out the common term (Total number of questions):
Total number of questions * (100 - 1) = 0
Simplifying further:
Total number of questions * 99 = 0
Finally, dividing both sides of the equation by 99, we get:
Total number of questions = 0 / 99 = 0
Therefore, based on the given information, it appears that the total number of questions on the practice test is 0. However, it is important to note that this result seems unlikely or there may be some missing information.
