The answer would be 25
9 times 2 is 18 plus 7 is 25
First row, the answer on the left , -5 3/4 - 4 2/3
She is incorrect cause if we take the number 20 and take 25% of it it equals 5 so now 20 is only 15. They if we take 75% away from 20 is equals 15 so then we only have 5 from 20 left. Therefore she’s incorrect because 75% leaves 5/20 and 25% leaves 15/20. Hope that makes sense.
