Guys pls help me im failing my grade and i really need help plsssss and dont do it for the points

Answer:
simplified: [tex]\frac{3}{5}[/tex]
unsimplified: [tex]\frac{12}{20}[/tex]
Step-by-step explanation:
Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:
15 - 3 = 12
The difference of the two fractions is [tex]\frac{12}{20}[/tex]. To simplify this answer, divide both the numerator and the denominator by 4:
12/4 = 3
20/4 = 5
The difference in simplified form is [tex]\frac{3}{5}[/tex].
I hope this helps. :)
