Hmm difficult one but I think ima have to go with 2?????
To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 5/8 as a percent, we need to find a fraction equivalent to 5/8 that has a 100 in the denominator. We can do this by setting up a proportion.
= 
<h3 /><h3>8n = 500</h3><h3>÷8 ÷8</h3><h3> n = 62.5%</h3><h3>Therefore, 5/8 is equal to 62.5%.</h3><h3 />
To write a fraction as a decimal, we can simply divide the numerator by the denominator.
5 ÷ 8 = 0.625
Therefore, 5/8 is equal to 0.625.

Answer:
2 gallons of pure alcohol
Step-by-step explanation:
Let x represent the number of gallons of pure alcohol needed, and create an equation:
4(0.25) + x(1) = (x + 4)0.5
1 + x = 0.5x + 2
x = 0.5x + 1
0.5x = 1
x = 2
So, 2 gallons of pure alcohol should be added.
