First, let's calculate the fraction of the class that are freshmen:
2/5
Next, let's calculate the fraction of the class that are sophomores:
1/4
Then, let's calculate the fraction of the class that are juniors:
1/10
To find the fraction of the class that are seniors, we need to subtract the sum of the fractions of the other three grades from 1:
1 - (2/5 + 1/4 + 1/10)
To simplify this, we find a common denominator, which in this case is 20:
1 - (8/20 + 5/20 + 2/20)
Now let's add the fractions to get the result:
1 - (15/20)
1 - 15/20
1 - 3/4
Finally, we subtract 3/4 from 1 to get the fraction of the class that are seniors:
1 - 3/4 = 1/4
Therefore, 1/4 of the class consists of seniors.
