0.3% = 0.003..." of " means multiply
0.003(200) = 0.6 <==

0.85% = 0.0085
0.0085(600) = 5.1 <==

what u can do to turn the percents to decimals is divide by 100.
0.3 / 100 = 0.003 and 0.85 / 100 = 0.0085
or u can move the decimal two spaces to the left

Option:

a. for every 13 dogs, there are 25 cats.

b. there are twice as many cats as dogs at the shelter.

c. the shelter has more dogs than cats.

d. there are 25 animals in the shelter.

Answer:

a. for every 13 dogs, there are 25 cats.

So;

$\frac{D}{C} = \frac{13}{25}$

By comparison:

$D=13$

$C = 25$

This implies that:

For every 13 D, there are 25 C

Hence: Option A is true
