1. D IVIDING F RACTIONS AND Cross Reducing

2. B ASIC F RACTIONS R EVIEW : *Change a whole # to a fraction  Write a 1 underneath *Change a fraction to a whole #  Drop the 1 or divide *Cross Reducing  -same #s, make both 1 - leave diagonal pair with “1” alone - see if diagonal pair can be reduced by smaller # 5 = 5 18 = 18 16 = 1 12 = 3 1. 5 5 7

3. R EVIEW OF D IVIDING F RACTIONS Steps: 1) KEEP [the first fraction the same] 2) CHANGE [the “ ÷ ” to “x”] 3) FLIP [the second fraction to its reciprocal] **CROSS REDUCE [before solving] 3 ÷ 3 4 12 3 x 12 4 3 1 x 3 1 1 3 1
