There is a bag with only red marbles and blue marbles. The probability of randomly choosing a red marble is 2 9 . There are 63 m
Tatiana [17]

The main idea is the number of marbles and the denominator of the probability. All you have to do is multiply the fraction by a fraction which is equal to 1 which makes the denominator equal to 63. We know 63 is a multiple of 9. 9 goes 7 times in 63 so we multiple the fraction \frac{2}{9} with \frac{7}{7} which gives, \frac{2 * 7}{9 * 7} which when evaluated gives \frac{14}{63} and the numerator is the number of red marbles in the bag. So there are 14 red marbles in the bag :D
