Multiply this by 100 to make it a whole number Division of Decimals Rule: 1. Make the DENOMINATOR a whole number by multiplying by 10, 100 or 1,000. 2. Multiply the top by the same amount 3. Divide as usual E.g. 2 1• 8 1 • 09 2 1 • 8 1 0 9 2 3 2 1 8 0 • 0 1 0 9 1 2 1 • 8 1 0 9 • 2 1 8 0 • 0 1 0 9 DENOMINATOR Multiply the top by 100 Multiply this by 100 to make it a whole number = 20 Click mouse for more Divide as usual

Try this. Now times this by the same 2 0 • 6 1 • 4 2 0 • 6 1 • 4 2 0 6 • 1 4 • 2 0 • 6 1 4 • 2 0 6 = 1 4 Now divide as usual What must you times this by Click the mouse to see answer 2 0 • 6 2 0 6 1 4 . 7 1 • 4 = 1 4 = Click for more

Try this Now times this by the same 4 1 • 6 3 2 • 4 1 • 6 3 2 • 4 1 6 • 3 2 • 4 1 6 = 3 2 4 1 • 6 3 • 2 4 1 • 6 3 • 2 Now divide as usual What must you times this by Click mouse to see answer 4 1 • 6 4 1 6 13 3 • 2 = 3 2 = Click for more

Try these. Click the mouse to see the answer Now times this by the same 4 5 • 0 6 2 • 1 2 4 5 0 6 • 2 1 2 • 4 5 0 6 = 2 1 2 4 5 • 0 6 2 1 2 • 4 5 • 0 6 2 1 2 • 4 1 • 0 6 2 • 1 2 Now divide as usual What must you times this by 4 5 • 0 6 4 5 0 6 2 1 • 2 5 2 • 1 2 = 2 1 2 = END
