First bring the 9m / 108m to a comparable value = 3m / 12m

Q1 = 3/20
Q2 = 3/12

Difference (3/20) â€“ (3/12) = 96/240 = 12/30 = 2/5 = 40% Decrease

Whatâ€™s the OA?

Sale 1st Q = 3/20 = .15

Sale 2nd Q = 9/108 = .083

((3/20) - (9/108)) * 100 / (3/20) = ( (324 - 180) * 100 / (20*108)) /(3/20)
(144*100)/(20*108) / (3/20)

144*100*20 / 20*108*3 = 44.44%
