Answer :
The problem involves finding the ratio of the number of students who used their computers to the total number of students surveyed.
Step 1: Determine the total number of students surveyed
There are 20 students surveyed. Thus, the total is
[tex]$$
\text{Total Students} = 20.
$$[/tex]
Step 2: Count how many students used their computers
A student is considered to have used their computer if they spent more than 0 hours on it. Checking the data, two of the students spent 0 hours on their computers. That means the number of students who used their computers is:
[tex]$$
\text{Students Who Used} = 20 - 2 = 18.
$$[/tex]
Step 3: Calculate the ratio
The ratio of students who used their computers to the total number of students is given by:
[tex]$$
\text{Ratio} = \frac{\text{Students Who Used}}{\text{Total Students}} = \frac{18}{20}.
$$[/tex]
The fraction [tex]$\frac{18}{20}$[/tex] can be simplified by dividing both the numerator and denominator by 2:
[tex]$$
\frac{18 \div 2}{20 \div 2} = \frac{9}{10}.
$$[/tex]
Thus, the final answer is:
[tex]$$
\frac{18}{20} \quad \text{or} \quad \frac{9}{10}.
