This is only possible if the quotient betwen 81 and 3 must be bigger than 27.

Lets do it:

natka813 [3]

Given:

About 3/5th of the registered voters participated in 2016 election.

California has 25 million registered voters.

To find:

The number of registered voters who participated in 2016 election.

Solution:

We have,

Total number of registered voters = 25 million

According to the question,

$\text{Registered voters who participated}=\dfrac{3}{5}\times \text{Total number of registered voters}$

Now,

$\text{Registered voters who participated}=\dfrac{3}{5}\times 25$

$\text{Registered voters who participated}=3\times 5$

$\text{Registered voters who participated}=15$

Therefore, there are 15 millions of registered voters who participated in 2016 election.
