0.01 written as a percent then round to the nearest tenth of a percent
Aleks [24]

Answer and step-by-step explanation:

To write it as percent, multiply it with 100, we get:

0.01 * 100 = 1%

Nearest tenth of a percent would be 10%, 20%, 30%, etc.

So as we can see 1% is nearest to 10% so we round it up to 10%

Hope this helped :3
