Grade 6 Mathematics
Dividing by a fraction is the same as multiplying by its reciprocal!
When you divide, you're asking: "How many groups of [the divisor] fit into [the dividend]?"
Use the Keep-Change-Flip method to divide any fractions!
The reciprocal is what you get when you FLIP a fraction upside down.
KEEP the first fraction: 23
CHANGE division (/) to multiplication (x)
FLIP the second fraction: 45 becomes 54
23 x 54 = 2 x 53 x 4 = 1012 = 56
First, convert mixed number to improper: 1 1/2 = 3/2
Now use Keep-Change-Flip: 3/2 / 3/4 = 3/2 x 4/3
32 x 43 = 126 = 2
WRONG: 2/3 / 4/5 = 3/2 x 4/5 (Flipped the first fraction - INCORRECT!)
RIGHT: 2/3 / 4/5 = 2/3 x 5/4 (Flip only the SECOND fraction!)
1. 34 / 12 = 34 x =
2. 56 / 23 =
Keep: _____ Change: / to x Flip: _____
3. 45 / 25 =
4. 214 / 38 =
First convert: 2 1/4 = _____
