  1. 10 2 = Division with Decimals What is division? means: how many piles of ….. can you make? This can be demonstrated using the denomination of cups Denomination is ‘what we are counting in’ 5

  2. 60 15 = 60 15 = 4 60 0 15 0 = 4 60 00 15 00 = 4 Division with Decimals When the numbers get bigger it is no longer practical to use or draw cups. However the principle stays the same. How many piles of 15 can we make? 15 15 15 15 4 piles so The denomination can be anything we want it to be: 60 pens can be put into 4 piles of 15 pens 60 tables can be put into 4 piles of 15 tables 60 tens can be put into 4 piles of 15 tens 60 hundreds can be put into 4 piles of 15 hundreds

  3. 0.6 0.2 6 tenths 2 tenths 6 2 = 6 0.2 = 60 2 = Division with Decimals Lets see how we can use this with decimals We can say that the denomination is tenths How many piles of 2 tenths can we make out of 6 tenths? So the calculation now becomes: 3 (piles of 2 tenths) This will be easier if we think about the denomination of the quotient (the amount of ‘cups’ that I want in a pile) In this case the quotient is 0.2 This is 2 tenths, therefore we need to start thinking tenths There are 60 tenths in 6 and 2 tenths in 0.2 so the calculation becomes: 30

  4. 240 ¸ 8 = 30 think hundredths Division with Decimals Now try these: 1. 8 ¸ 0.2 = 2. 12 ¸ 0.4 = 3. 1 ¸ 0.5 = 4. 2 ¸ 0.4 = 5. 6 ¸ 0.3 = 6. 5 ¸ 0.02 = 7. 10 ¸ 0.05 = 8. 18 ¸ 0.03 = 9. 1.8¸ 0.6 = 10. 2.4¸ 0.08 = 80 ¸ 2 = 40 think tenths 120 ¸ 4 = 30 think tenths 10 ¸ 5 = 2 think tenths 20 ¸ 4 = 5 think tenths 60 ¸ 3 = 20 think tenths 500 ¸ 2 = 250 think hundredths 1000 ¸ 5 = 200 think hundredths 1800 ¸ 3 = 600 think hundredths 18 ¸ 6 = 3 think tenths Can you see a quick way of finding the correct calculation?

  5. 9506 7 = 7 9 5 0 6 Now try these: • 8 = • 9 = • 8472 12= Division with Decimals Harder Division 1358 Draw the division box with the divisor outside 1 5 8 3 2 4 5 106 107 806

  6. Division with Decimals Now try these: • 8 = • 9 = • 8472 12=
