Hi, I’m having trouble with the following ratio question from the google form.

Yesterday, the ratio of dogs to cats was 4:7. Today, the ratio of dogs to cats is 5:6. The ratio today is what percent larger than the ratio yesterday?

I thought the ration increased from 4/11 to 5/11 to the change is 1/11, which means the an increase of 9%…but the correct answer is 46%. Can someone help me understand?
