Question

The ratio of dogs to cats being treated at a veterinarian's office this week is 5 : 2. Suppose there are 168 dogs and cats scheduled to be treated during the week. How many cats would you expect to be treated?___ cats

Answer 1

Answer:

48 cats

Step-by-step explanation:

Am interesting factoid about ratios:

The ratio $a:b$ can be separated into fractional parts of $\frac{a}{a + b}$ and $\frac{b}{a + b}$. We need to know the cat part. $\frac{2}{5 + 2} = \frac{2}{7}$, so that is the fraction part. Then, we multiply this fraction by 168 to get the total number of cats. This number is 48.
