        b = c
    return a

mu = 1
for i in s:
    i = i.split("/")
    mu = mu * int(i[1])
zi = 0
for i in s:
    i = i.split("/")
    zi = zi + int(i[0]) * mu // int(i[1])

t = gcd(abs(zi), mu)
zi = zi // t
mu = mu // t

if zi == 0:         # 为零的情况,测试点6
    print(0)

flag = False
if abs(zi) >= mu:       # 分子为负数的情况，测试点4.5
    print(zi//mu, end="")
    flag = True


if abs(zi)%mu != 0:
    if flag:
        print(end=" ")
