Question

Choose the following ratios as a percent: 30 days out of 100 days

10%
30%
100%
3%

Answer 1

30%

Explanation:

30% of 100 in simple terms stands for; "Thirty percent of a hundred."

This shows the ratio percentage correctly. And other choice would not be correct.

100% of 100 has nothing to do with 30.

3% is "three percent of 100." And again, has nothing to do with thirty.

10% also has nothing to do with thirty.
