Answer:
25/8 or 3 1/8
Step-by-step explanation:
5/8 * 5/1 (aka 5)
5/1 equals to 5 because any whole number over 1 equals the same whole number.
To multiply fractions, just multiply across. In the case. 5 time 5 for the numerator. Then 8 times 1 for the denominator.
= 25/8 = 3 1/8
3 1/8

Work Shown:
n = number of sides = 9
S = sum of the interior angles of any polygon with n sides
S = 180(n-2)
S = 180(9-2)
S = 180(7)
S = 1260
