taurus [48]

Answer:

<h2>21.4368 ≅ 21.44 million households owned at least two cats.</h2>

Step-by-step explanation:

Total number of households were 116 million.

Hence, 100% = 116 million.

33% of the total US households owned at least one cat.

Hence, the number of household having at least one cat is \frac{33\times116}{100} = \frac{3828}{100} = 38.28 million.

It is also given that 56% of that 38.28 million households owned at least 2 cats.

Hence, the number of households having 2 cats is \frac{56\times38.28}{100} = \frac{2143.68}{100} = 21.4368 million.
