I do not get this question

Answer 1

35%

Explanation:

The overall percentage must add up to 100%

Because of this...

100% (total) - 49% (swimming) = 51%

51% - 16% (biking) = 35% (rollerblading)

Answer 2

Well the total amount is gonna be 100%.
Take away 49% for swimming and another 16% for biking and u get the percent of who voted for rollerblading.

100% - 49% - 16% = 35%
