Answer:
.1 (or 1/10)
Step-by-step explanation:
3 * 10^9 = 3 * 10^8/x
<em>Use PEMDAS to interpret</em>
3* 10^9 = 3 * (10^8)/x
<em>Divide both sides by 3</em>
10^9 = (10^8)/x
<em>Divide both sides by 10^8</em>
10 = 1/x
<em>Find the reciprocal of both sides</em>
1/10 = x

Let there be x quarts of the 20% salt solution, and (25 - x) quarts of the 80% salt solution.
Then the total amount of salt in the 20% portion would be 0.2x, while that from the 80% portion would be (0.8)(25 - x). This would have to total up to (0.44)(25) in the final solution, so the equation is:
0.2x + 0.8(25 - x) = (0.44)(25)
-0.6x + 20 = 11
x = 15 quarts of the 20% salt solution
25 - x = 10 quarts of the 80% salt solution
