It should be relatively large, and it is better to compare scores and use general scoring methods, which are also commonly used.

Bear: 7/20 tons =7/20= 14/40.

Orangutan: 9 out of 40 tons =9/40.

Hippo: 3/8 ton =3/8= 15/40.

Elephant: 3/5 =3/5=24/40.

After comparison, it is found that the elephant has the largest lift, and then it is compared with the tiger. . .

Elephant: 3/5 =3/5=27/45.

Tiger: 4/9 tons =4/9=20/45.

I found it was the biggest tiger. . .
