Question

The ratio of red marbles to blue marbles in a bag is 2 to 5. If there are 60

more blue marbles than red marbles in the bag, how many marbles are
there all together?​

Answer 1

84 in all.

Explanation:

if there are 2 red marbles to every 5 marble than 60 / 5 = 12, 12 x 2 = 24 + 60 = 84.

Answer 2

140

Explanation:

Let's call the red and blue marbles 2x and 5x. We know that 5x = 2x + 60, so x = 20. The sum of all marbles in the bag is 2x + 5x = 7x which is 7 * 20 = 140 marbles. Hope this helps!
