Answer :
An equivalent fraction of students that does not be a part of students who attended choir practice is given by 1/4 or 0.25 as a decimal.
Total number of students are equal to 20.
If 15 out of 20 students attended choir practice.
Then the fraction of students who attended can be written as 15/20.
An equivalent decimal fraction that does not represent the part of students who attended choir practice is
= Subtract the fraction of students who attended from 1 which represents the whole group of students.
= 1 - 15/20
= 20/20 - 15/20
= 5/20
= ( 1/ 4) as simplified fraction form.
= 0.25 as a decimal
Therefore, equivalent decimal fraction of students does not represent part of students who attended choir practice is 1/4 or 0.25 as a decimal.
