Answer:
10
Step-by-step explanation:
The answer is 10 because there are 20 days and no home work is due on 7 of those days so that’s 13 days with homework from math or writing. Then you take the three days where it was just math and subtract that to get 10 days of writing.
25 students.....10 of which passed...
percentage of students that passed : 10/25 = 0.4 = 40% <==
I feel like it would be rational because 0/12 = 0, and 0 is a rational number.
