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?

Math 
Steve,
m/k = 12/7
k32 = 5/7 k
so, 2/7 k = 32
k = 112
m/112 = 12/7
m = 192
so, in the beginning
mk = 80
Maya had 80 more beads than Kayla
Now,
(m+28)/(k32) = 220/80 = 11/4
