Answer:
0.90
Explanation:
Just like a decimal to a percentage number, you must multiply by 100. By converting a percentage number to a decimal point, you must divide it by 100. Which means, the decimal must move 2 times.
For example,
0.90 x 100 = 90%
This is decimal to percentage number, but in this case it is percentage to decimal.
90%.
Since the number ended at 0, put the decimal there and move it 2 times to get to your decimal point.
.90 = 0.90
There you'll get your answer! ^^
90% = 0.90
