Start feeding it with 1:1 ratios of flour and water.  After two feedings it is going to be 100%.  No math required.

any amount. example: take 30g of starter, feed 100g flour and 100g water. Voila. 

To clarify an important point often overlooked:

100% starter means equal parts flour and water by weight not by volume. If you continue to use volume measurements you'll have to adjust because flour weighs a lot less than water for the same volume.

See this: Converting starter hydrations: A Tutorial. Or through thick and thin and vice versa

What suave suggested is generally sufficient, however.

i usually feed my starter which is 9 ounces with 1.12 pounds flour and 1.3 water. Im bad at math so how much starter should i use and fed with equal parts? thanks so much!

Looks like you're making a lot of starter, you must bake a lot!

If you start with 9oz of starter, then just feed 1.12lbs flour and 1.12lb water on your next feed.

Ideally, you should alter the seed amount so that the starter peaks and is ready to be fed again at the same time that you would  like to  feed it.  For example, if you are planning to feed it one pound each of flour and water, and you want to feed it twice a day (or once or three times, the choice is yours), then the correct amount of seed is the amount that will cause the starter to reach peak activity just before you're ready to feed it again.   This seed amount may change as ambient temps and humidity change. 

If you're not a pro baking large quantities of bread, then you might also consider reducing the size of your starter dramatically.  Silverton's quantities are huge, but if you're switching to a 100% hydration and perhaps going to explore other books, feel free to cut back.  I always feed my starter with 50g of flour (hydration varies with what I'm making) and seed quantity is 10g for a 12 hour schedule, or only 5g for a 24 hour schedule.
