Answer:
53% are tigers
Explanation:
If you were referring to the question:
An animal park has lions, tigers and zebras. 17% of the animals are lions and 3/10 of the animals are zebras. What percentage are tigers? Show me your work!
We can then solve it by considering what is 3/10 in percent form.
When you think of percent, just remember that it is a portion for every 100. So think of a fraction that is proportional to 3/10 that is a fraction of 100:

So 3/10 = 30/100 which in percentage form is 30%.
Now if:
17% = lions
30% = zebras
We can get the percentage by looking for how many out of 100% is left.
100% - (17% + 30%)
100% - 47%
53%
