There are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies.
4/25 prefered digital copies
21/25 prefered hard copies

sum = 60
let the number removed be x , then

60 - x = 44 ( subtract 60 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
The number removed was 16
