Question

What is 8.6% as decimal

Answer 1

Just put the point 2 times to the left because 100 have 2 zero ..

Answer 2

8.6% as a decimal is 0.086.

Percent means 'per 100'. So, 8.6% means 8.6 per 100 or simply 8.6/100.
If you divide 8.6 by 100, you get 0.086 (a decimal number).

You could also remove the percent symbol, then move the decimal point two places to the left.
