PSLE Andy kept his blue and brown beads in two boxes. The ratio of the number of blue to brown beads in the first box was 5 : 6 and it was 1 : 2 in the second box. The two boxes contained the same number of beads. What fraction of Andy's beads were brown beads?

The total number of beads in the first box and the second box is the same. Make the total number of beads in each box the same.
LCM of 11 and 3 is 33.
Total number of brown beads
= 18 u + 22 u
= 40 u
Total number of beads
= 33 u + 33 u
= 66 u
