Q. 6 toy cars are in 16in

16 divided by 6=2.66 cars p/in

How many in 64in = 64x2.66=24 cars
40in = 40x 2.66= 15 cars
104" = 104 x 2.66= 39cars

Explanation
64inches* 6cars/16inches = notice how the units inches divide out, and leaves the unit cars....

Do you mean to set up like algebra?

64in=6cars div by 16 in
I'm confused..I know in alg u do the opposite on the oth side but all I hv ever done is sub on 1 sd then add on the other or vise versa. I don't know if I multiply and what do I multiply. I think I prob making it more confus than it is..thank you for all the help
