Final answer:
To determine the ratio of all dogs to Dobermans when the ratio of German shepherds to Dobermans is 4 to 3, add both numbers to get the total number of dogs and compare it to Dobermans, resulting in a ratio of 7:3.
Step-by-step explanation:
If the ratio of German shepherds to Dobermans is 4 to 3, we need to find the ratio of all dogs to Dobermans. Assuming all the dogs are either German shepherds or Dobermans, we add the number of German shepherds and Dobermans together to find the total number of dogs.
Let's say there are 4 German shepherds and 3 Dobermans.
To find the ratio of all dogs to Dobermans, we add the number of German shepherds (4) to the number of Dobermans (3), giving us a total of 7 dogs.
Hence, we would have a ratio of 7 dogs to every 3 Dobermans, which simplifies to the ratio of 7:3.
The process to calculate this involves:
Adding the number of German shepherds (4) and Dobermans (3) together.
Expressing that total number in relation to the number of Dobermans (3).
