Step-by-step explanation: I used proportions to solve this. 100% and 8 are the same because 100% was what she thought the weight of the cat was. So this is one side of the proportion. The other side, we need a variable which is X. X is the unknown percentage. X is equal to 10. I then did 100% x 10 which is 1000 then divided it by 8 which is equal to 125%. 125% - 100% = 25%.
