Answer is
Improper fraction: 5/4
Mixed number: 1 1/4
.25= 1/4
Since 1/4 is just 1 divided by 4 which is .25
Now you just keep the whole number and change the decimal into a mixed number.
Now to change it into an improper fraction multiply denominator by whole number and then add numerator.
4 x 1 + 1= 5
So 5/4
