Let us consider two irreducible fractions. The denominator of the first one is equal to 1400,and the denominator of the second to 6100. What is the smallest possible denominator of a fraction equal to the sum of these fractions, after the fraction is reduced? (For example, \frac{2}{3} + \frac{8}{15} = \frac{18}{15} = \frac{6}{5}, and the denominator after the reduction is equal to 5.) |
