+23252 For these problems, find the difference between the incorrect answer and the correct answer (subtract, if the answer is negative, ignore the negative sign); divide this difference by the correct answer, and multiply by 100.
Board: 13.2 - 12.0 = 1.2 ---> 1.2/12 = 0.10 ---> 0.10 x 100 = 10%
Dog food: 11.5 - 10 = 1.5 ---> 1.5/10 = 0.15 ---> 0.15 x 100 = 15%
Can you do the other two?
