Answer:
0.25%
Step-by-step explanation:
To convert a fraction to percent, you simply have to multiply it by 100.
That is because the formula for percent is:
[tex]\frac vt \times 100 = p[/tex]
Where v is some value, t is the total value, and p is the percentage. Since we're given v/t (the fraction 0.0025), we can just multiply it by 100 to get p.
0.0025 * 100 = 0.25%
