25%½ to decimal

$${\sqrt{{\frac{{\mathtt{25}}}{{\mathtt{100}}}}}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}} = {\mathtt{0.5}}$$

25% and 1/2?

sorry larry, but your wording made no sense

I think you may mean 25.5%, in which case:

25.5% = 25.5/100 = 51/200

Ooops didn't answer the question :)

It is 0.255. As a fraction it is: 25.5/100, so divide by 100. This is easily done by moving the decimal place over 2 to the left.

.255

100 percent is always 1. So anything less than 100 percent is 0. something. In this case, 0.255
