Question: 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?
Solution:
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.
Answer: 60
