Question 981493: Fiona is making a bracelet. For every 2 red beads, she is using 3 green beads and 4 yellow beads. How many yellow beads does she need, if the total number of beads in the bracelet is 63?
I think there is a mistake in this question. Anyway I got 32. I think the total should be 64 not 63.

ratio is 2:3:4
7 times of the ratio is 14:21:28. There are 28 yellow beads.
There are 21 green beads
There are 14 red beads
The total needs to be a multiple of the sum of the numbers in the ratio.
