Answer:
48 cats
Step-by-step explanation:
Am interesting factoid about ratios:
The ratio [tex]a:b[/tex] can be separated into fractional parts of [tex]\frac{a}{a + b}[/tex] and [tex]\frac{b}{a + b}[/tex]. We need to know the cat part. [tex]\frac{2}{5 + 2} = \frac{2}{7}[/tex], so that is the fraction part. Then, we multiply this fraction by 168 to get the total number of cats. This number is 48.
