Heloise has dogs and cats in the ratio of 10:17, with the total number of pets being 189. If she gives 10 dogs to her friend Janet, how many dogs does she remain with altogether? Think carefully first, then make a decision:
The total ratio for the number of cats and dogs that Heloise has is 10 + 17 = 27. From the ratios, the fraction representing the number of dogs is 10 / 27, and this represents 10 / 27 * 189 = 70 dogs. If Heloise gives 10 of her dogs to Janet, she remains with 70 - 10 = 60 dogs. So, the answer is 60.
