Best ResponseYou've already chosen the best response.0I FOUND THE SOLUTION ONLINE BUT CAN'T UNDERSTAND HOW THEY CAME UP WITH B/G Solution Let g, b and y be the numbers of green, blue and yellow balls respectively. Using the given ratios, we can write the following fractions g / b = 2 / 7 and g / y = 3 / 5 The first fraction gives b / g = 7 / 2 We now evaluate the product of fractions g / y and b / g as follows (g / y) * (b / g) = (3 / 5) * (7 / 2) Note that (g / y) * (b / g) simplifies to b / y, hence b / y
