Turn both into improper fractions- there easier to work with that way 3 15/16 — 63/16 2 1/4 — 9/4 Then, set it up- you multiply by the reciprocal 63 Divided by 9 __. __ 16. 4 Multiply by reciprocal (flipped-second fraction) 63. x. 4 16 9 Cross product- check to see if diagonally the numbers have similar factors- 63 and 9 have 9 in common, 16 and 4 have 4 in common 7. 1 4. 1 1 3/4
