You were assigned 20 practice problems. You completed 5 problems. What fraction of the assigned problems do you have left?
the answer is: 3/4
(20 - 5) / 20 = ?
there are 15 left, so 15/20
you may want to reduce that to lowest terms ...
how would it be 15/20

To find the fraction of the assigned problems that you have left, you need to compare the number of problems you have left to the total number of assigned problems.
Given that you were assigned 20 practice problems and you completed 5 problems, you have 20 - 5 = 15 problems left.
So the fraction of assigned problems that you have left is 15/20.
To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 5 in this case.
Dividing 15 by 5 gives you 3, and dividing 20 by 5 gives you 4.
Therefore, the fraction 15/20 can be simplified to 3/4.
Thus, you have 3/4 or three-fourths of the assigned problems left.
