Solve for p:

p/8 + 3/8 = 25/8

p/8 + 3/8 = (p + 3) / 8:

(p + 3) / 8 = 25/8

Multiply both sides of (p + 3) / 8 = 25/8 by 8:

(8 (p + 3)) / 8 = (8*25) / 8

(8*25) / 8 = (8*25) / 8:

(8 (p + 3)) / 8 = (8*25) / 8

(8 (p + 3)) / 8 = 8/8 * (p + 3) = p + 3:p + 3 = (8*25) / 8

(8*25) / 8 = 8/8*25 = 25:

p + 3 = 25

Subtract 3 from both sides:

p + (3 - 3) = 25 - 3

3 - 3 = 0:

p = 25 - 3

25 - 3 = 22:

Answer: p = 22
