To determine how many questions Giselle has left to do on her 25-question test, let's break down the problem step by step:
1. Identify the total number of questions on the test:
Giselle's test has a total of 25 questions.
2. Determine the percentage of questions she has completed:
Giselle has completed 60% of the test.
3. Calculate the number of questions she has completed:
To find out the number of questions completed, we multiply the total number of questions by the percentage completed (converted to a decimal):
[tex]\[
\text{Number of completed questions} = 25 \times \frac{60}{100}
\][/tex]
4. Figure out the number of completed questions:
When we carry out the multiplication, we get:
[tex]\[
\text{Number of completed questions} = 25 \times 0.60 = 15.0
\][/tex]
So, Giselle has completed 15 questions.
5. Calculate the remaining questions:
To find out how many questions she has left, we subtract the number of completed questions from the total number of questions:
[tex]\[
\text{Remaining questions} = 25 - 15
\][/tex]
6. Calculate the result:
[tex]\[
\text{Remaining questions} = 10.0
\][/tex]
Therefore, Giselle has 10 questions left to complete on her test.
