Take 38.1 and put it in fraction form in like 38.1/10 then take 984.6 and put it in fraction form like 4923/5 then you take 4923/5 and do KCF which stands for Keep. Change. Filp., then you should get 38.1/10 × 5/4923 then you cross out 10 and 5 then get 381/2×1/4923 then cross out 381 and 4923 then get 127/2 × 1/1641 then multiply across then get 127/3282 then that your answer! :)
