Solve: 1/2 ÷ 1/4. Use keep, change, flip.
Ask how many fourths fit into one half.
Keep 1/2, change division to multiplication, and flip 1/4 to 4/1. Then 1/2 × 4/1 = 4/2 = 2, so the answer is 2. - 2
Solve: 3/4 ÷ 1/2. Show the keep, change, flip step.
Keep 3/4, change division to multiplication, and flip 1/2 to 2/1. Then 3/4 × 2/1 = 6/4 = 3/2, so the answer is 1 1/2. - 3
Solve: 2/3 ÷ 1/6. Simplify your answer.
The flipped fraction of 1/6 is 6/1.
Keep 2/3, change division to multiplication, and flip 1/6 to 6/1. Then 2/3 × 6/1 = 12/3 = 4, so the answer is 4. - 4
Solve: 4/5 ÷ 2/5. Write the multiplication problem you use.
Keep 4/5, change division to multiplication, and flip 2/5 to 5/2. Then 4/5 × 5/2 = 20/10 = 2, so the answer is 2. - 5
Solve: 5/6 ÷ 1/3. Simplify your answer.
After multiplying, divide the numerator and denominator by their greatest common factor.
Keep 5/6, change division to multiplication, and flip 1/3 to 3/1. Then 5/6 × 3/1 = 15/6 = 5/2, so the answer is 2 1/2. - 6
A recipe uses 3/4 cup of flour. Each small scoop holds 1/4 cup. How many small scoops are needed?
This is 3/4 ÷ 1/4. Keep 3/4, change to multiplication, and flip 1/4 to 4/1. Then 3/4 × 4/1 = 12/4 = 3, so 3 small scoops are needed. - 7
Solve: 7/8 ÷ 1/4. Give your answer as a mixed number.
Change 28/8 to a simpler fraction before writing a mixed number.
Keep 7/8, change division to multiplication, and flip 1/4 to 4/1. Then 7/8 × 4/1 = 28/8 = 7/2, so the answer is 3 1/2. - 8
Solve: 2/5 ÷ 3/10. Simplify your answer.
Keep 2/5, change division to multiplication, and flip 3/10 to 10/3. Then 2/5 × 10/3 = 20/15 = 4/3, so the answer is 1 1/3. - 9
A ribbon is 2/3 meter long. You cut it into pieces that are each 1/6 meter long. How many pieces can you make?
Think of counting how many 1/6 meter pieces fit inside 2/3 meter.
This is 2/3 ÷ 1/6. Keep 2/3, change to multiplication, and flip 1/6 to 6/1. Then 2/3 × 6/1 = 12/3 = 4, so you can make 4 pieces. - 10
Solve: 3/5 ÷ 2/3. Simplify your answer.
Keep 3/5, change division to multiplication, and flip 2/3 to 3/2. Then 3/5 × 3/2 = 9/10, so the answer is 9/10. - 11
Solve: 6/7 ÷ 3/14. Show each step.
You can simplify before multiplying because 14 and 7 have a common factor.
Keep 6/7, change division to multiplication, and flip 3/14 to 14/3. Then 6/7 × 14/3 = 84/21 = 4, so the answer is 4. - 12
Maya has 5/6 of a yard of string. Each bracelet needs 1/3 of a yard. How many bracelets can Maya make?
A real bracelet must be whole, but the fraction tells how many bracelet lengths fit in the string.
This is 5/6 ÷ 1/3. Keep 5/6, change to multiplication, and flip 1/3 to 3/1. Then 5/6 × 3/1 = 15/6 = 5/2, so Maya can make 2 1/2 bracelets worth of string. She can make 2 whole bracelets with some string left over.
