The ratio of Maya's beads to Kayla's beads was12:7. After Maya bought another 28 beads and Kayla gave away 32 beads, 5/7 of Kayla's beads were left. How many more beads did Maya have than Kayla in the beginning? Find the ratio of Maya's beads to Kayla's beads?

m/k = 12/7

k-32 = 5/7 k
so, 2/7 k = 32
k = 112

m/112 = 12/7
m = 192

so, in the beginning
m-k = 80
Maya had 80 more beads than Kayla

Now,

(m+28)/(k-32) = 220/80 = 11/4
