There are 7 girls and each girl has 2 legs, so that's automatically 14 legs. Each girl has 7 backpacks, so there are 787 = 49 backpacks on the bus. In each backpack, there are 7 big cats, so there are 49*7 = 343 big cats on the bus. Each cat has 4 legs, so there are 343*4 = 1,372 big cat legs. For every big cat, there are 7 little cats, so there are 343*7 = 2,401 little cats. Again, each little cat has 4 legs, so there are 2,401*4 = 9,604 little cat legs. Now add up all the legs:
14 + 1,372 + 9,604 = 10,990 legs <===ANSWER
14 + 1,372 + 9,604 = 10,990 legs <===ANSWER

You have the girls' legs, big cat legs and little cat legs.
1. girls 14 X 2 = 14
2. big cats 7 X 7 X 7 = 343 cats X 4=1,372
3. little cats 7 X 7 X 7 X 7 = 2,401 cats X 4 = 9,604
9,604 + 1,372 + 14 = 10,990 legs
1. girls 14 X 2 = 14
2. big cats 7 X 7 X 7 = 343 cats X 4=1,372
3. little cats 7 X 7 X 7 X 7 = 2,401 cats X 4 = 9,604
9,604 + 1,372 + 14 = 10,990 legs

7x2= 14
343x4= 1372
2401x4= 9604
14+1372+9704=10990
343x4= 1372
2401x4= 9604
14+1372+9704=10990
2008-08-16 4:44 pm
7 x 2 + 7 x 7 x 7 x 4 + 7 x 7 x 7 x 7 x 4
= 14 + 1372 + 9604
= 1386 + 9604
= 10990 legs
= 14 + 1372 + 9604
= 1386 + 9604
= 10990 legs

7girls* 2 legs=14 legs.
7 cats * 2=14legs
49*2= 98
14+12+ 98= 124 leg in all
7 cats * 2=14legs
49*2= 98
14+12+ 98= 124 leg in all
