A good repeating decimal would be pi.
Answer:
There are multiple ways to do so:
You can divide the number by 100 to convert it to a decimal
You could take your percentage and add a decimal two places to the left.
Examples of both:
For division its as simple as 75 divided by 100 = 0.75
If we are going to use the decimal method, lets say we have 45%, so we can do this:
45% =45.00
Move the decimal two places to the left.
0.45
