There are 7 girls on a bus. Each girl has 7 backpacks and in each backpack there are 7 big cats. For every big cat there are 7 little cats. How many legs are there in the bus?

None, buses have wheels.

the answer is 11,970 legs on the bus !!! the answer is 11,970 legs on the bus !!! the answer is 10304 legs the answer is 14 legs the answer is 9618 Legs the answer is 70 the answer is 10304 The answer is 1472 ? the answer is 0 legs on the bus !! _______ Alright. To work this out, it helped me to work backwards. Let's start with how many legs there are in total from the little cats. Per big cat would be 28 (4 legs*7 cats=28 legs). Per backpack you would have to multiply it by 7 more (for each backpack, so 28 times 7 equals 196). Now each girl has 7 backpacks, so you multiply it by 7 (196*7=1372). Then per girl would be 1372 times 7 equals 9604, which is the total number of SMALL cat legs on the bus. Then, to find out the number of big cats, we would work the same way: 4*7=28 for each backpack 28*7=196 for each girl 196*7=1372 Total BIG cat legs Next, we'd have to find the number of girl's legs. 7*2=14. Add it up: 9604+1372+14=10,990 There you are. 10,990 is the total number of legs. ------------------------------------------------------------------------------------------------------------- I got 10,990 legs, and here is the system I used. There are 7 girls, each girl with 7 backpacks, leaving you with 49 back packs. For each backpack, there are 7 big cats, leaving you with 343 big cats. (49*7). For each big cat, there are 7 little cats, leaving you with 2401 little cats. (343*7) Now add the girls, big cats, and little cats, and you get 2751. (7+343+2401) Now take 7 (girls) out and multiply that by 2, and you get 14 legs. As for the remaining number (2744), multiply that by 4, and you get 10,976 legs. Now add the girl legs and the cat legs together and you get a total of 10,990, same as the one above me, only a different, maybe easier equation.
