Answer :
The two ratios you have provided are not related. Therefore, we can conclude that the two ratios are not related.
The first ratio, 15 out of 20 students own hand-held games, can be expressed as 3/4. The second ratio, 105 out of 160 students own hand held games, can be expressed as 21/32.
If the two ratios were related, then we would expect them to be equal or at least proportional. However, 3/4 is not equal to 21/32, and it is not proportional to it either.
Another way to think about it is that the first ratio represents the percentage of students in a group of 20 who own hand-held games. The second ratio represents the percentage of students in a group of 160 who own hand-held games.
The two groups of students are not necessarily the same, so we cannot compare the two ratios directly.
Therefore, we can conclude that the two ratios are not related.

The total number of students in the class is 140.
To find the answer, we can use proportions to solve for the total number of students in the class.
We can set up the proportion 15/20 = 105/x,
where x represents the total number of students in the class.
Cross-multiplying gives us 15x = 105*20.
Simplifying,
we find that x = 140.
Therefore, the total number of students in the class is 140.
