Question

Help me, but the answer is not E.

Answer 1

40%

Explanation:

To find the percentage difference between the families with 2 dogs and the families with no dogs, we need to find their difference first.

Difference = 45 - 27

= 18

Now that we know the difference, we just have to put the difference over the total as a fraction and multiply by 100%.

Percentage difference =
`(18)/(45)` × 100%

= 40%
