A random sample of dogs at different animal shelters in a city shows that 12 of the 65 dogs are puppies. The city's animal shelters collectively house 1,690 dogs each year. About how many dogs in all of the city's animal shelters are puppies?

Respuesta :

65 because you add then subtract so the you go back to 65
1690 divided by 65 = 26
26 x 12 = 312
