Solution for 1 is what percent of 25000:

1:25000*100 =

(1*100):25000 =

100:25000 = 0.004

Now we have: 1 is what percent of 25000 = 0.004

Question: 1 is what percent of 25000?

Percentage solution with steps:

Step 1: We make the assumption that 25000 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=25000$.

Step 4: In the same vein, $x\%=1$.

Step 5: This gives us a pair of simple equations:

$100\%=25000(1)$.

$x\%=1(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{25000}{1}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{1}{25000}$

$\Rightarrow x=0.004\%$
