hehe i think phantom is asking how we go from a decimal to a percent...

Okay so first it helps to understand "percent" 
"cent" means 100. So percent mean that many parts per 100. 

"I have 50% of a pizza" means:
"If a whole pizza is 100 parts, I have 50 of them"

we can also change numbers to a percent.

Since we usually consider 1 pizza 100% of a pizza, we can think of 1 as 100%

If we have less than 1 we have less than 100%

"How many percent is .50?"  
".5 of 1 is the same as 50 of 100"
so 50%

the trick is to just multiply by 100

.5 x 100 = 50%

.35 is how many percent?

.35=35%

1.45 is how many percent?

145%

Hope that helped
