    from fractions import Fraction
from functools import reduce

def product(fracs):
    t = reduce(lambda x, y : x * y, fracs)
    return t.numerator, t.denominator

if __name__ == '__main__':
    fracs = []
    for _ in range(int(input())):
        fracs.append(Fraction(*map(int, input().split())))
    result = product(fracs)
    print(*result)

    This is easy one and simple logic! The one fraction value in fracs is passed to x and another passed to y. Then it will multiplied and remaining also multiplied with answer. now we get multiplication of fraction. This value is reduced using reduce() to find numerator and denominator

    from fractions import Fraction
from functools import reduce

def product(fracs):
    t = reduce(lambda x,y: x*y,fracs)
    return t.numerator, t.denominator

if __name__ == '__main__':
    fracs = []
    for _ in range(int(input())):
        fracs.append(Fraction(*map(int, input().split())))
    result = product(fracs)
    print(*result)

    def product(fracs):
    pro = fracs[0]
    for frac in fracs[1:]:
        pro *= frac
    return pro.numerator, pro.denominator
