In bag K, 3/8 of the marbles are red. In bag M, 1/2 of the marbles are red. Bag K has four times as many red marbles as bag M. If the two bags were combined, what is the percentage of red marbles in the bag?(adsbygoogle = window.adsbygoogle || []).push({});

My work:

Say we had 6 red marbles in bag M. This means that bag K must have 24 red marbles. If this is the case, then we can say that 3/8=24/x

solving for x, we get 64 marbles total for bag K

if both bags were combined, then we would get 24+6 red marbles and 64+12 total marbles.

the ratio of red to total marbles is 30/76=39%

did I do this problem correctly?
