Seven girls on the bus 7 x 2= **14 legs**

Seven girls x seven backpacks = 49 backpacks

49 backpacks x 7 cats = 343 cats

343 cats x 4 legs each cat =** 1,372 legs**

343 cats x 7 kittens = 2, 401 kittens

2,401 kittens x 4 legs = **9,604 legs**

**14 girls' legs + 1,372 cats' legs + 9,604 kittens' legs + 2 bus driver's legs = 10,992 legs total**

driver= 2 legs

1girl= 2legs

7 girls= 2*7= **14 legs**

1 girl= 7 backpacks

7 girl= 7*7= 49 backpacks

1backpack= 7 cats

49 backpacks= 49*7= 343 cats

1cat= 4legs

343 cats= 4*343= **1372 legs**

1 cat= 7 kittens

343 cats= 7*343= 2401 kittens

1 kitten= 4 legs

2401 kittens= 4*2401= **9604 legs**

total legs= 9604+1372+14+2

=** 10992 legs**
