11. Tuesday, Oct 6 Lesson 3.6/3.7 Estimate and Divide Decimals by Whole Numbers

12. Divide Decimals by Whole Numbers Objective: To understand how to estimate and divide decimals by whole numbers.

13. Divide Decimals by Whole Numbers When estimating quotients, use a comparable number that is in the multiples list of the divisor. Example 8.6 ÷ 2 ≈ 8 ÷ 2 = 4 8 is a comparable number to 8.6 and is easily divisible by 2.

14. Divide Decimals by Whole Numbers When dividing a decimal by a whole number, divide as with whole numbers. Then place the decimal point in the quotient directly above it’s place in the dividend.

15. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ Estimate. What is a comparable number for 6.8 that is divisible by 2 (in the multiples list of 2) ?

16. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 Estimate. What is a comparable number for 6.8 that is divisible by 2 (in the multiples list of 2) ? 6 ÷ 2 = 3

17. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 Dividing a Decimal by a Whole Number. Step 1 – Place the numbers in the dividing bracket.

18. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 2)6.8 Dividing a Decimal by a Whole Number. Step 1 – Place the numbers in the dividing bracket.

19. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 2)6.8 Note – the first number in the expression ALWAYS goes inside the bracket.

20. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 2)6.8 Dividing a Decimal by a Whole Number. Step 2 – Divide and ignore the decimal point.

21. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 3 4 2)6.8 -6 08 -8 0 Dividing a Decimal by a Whole Number. Step 2 – Divide and ignore the decimal point.

22. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 3 4 2)6.8 -6 08 -8 0 Dividing a Decimal by a Whole Number. Step 3 – Bring the decimal point to the quotient, directly above the dividend.

23. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 3.4 2)6.8 -6 08 -8 0 Dividing a Decimal by a Whole Number. Step 3 – Bring the decimal point to the quotient, directly above the dividend.

24. Divide Decimals by Whole Numbers Find 6.8÷ 2 ≈ 3 3.4 2)6.8 -6 08 -8 0 It is very important the digits are lined up in the bracket!

25. Divide Decimals by Whole Numbers Round to the nearest tenth, if necessary. 8.4÷ 3 ≈ Estimate?

28. Divide Decimals by Whole Numbers Round to the nearest tenth, if necessary. 8.4÷ 3 ≈ 3 Step 1?

29. Divide Decimals by Whole Numbers Round to the nearest tenth, if necessary. 8.4÷ 3 ≈ 3 3)8.4 Step 2?

30. Divide Decimals by Whole Numbers Round to the nearest tenth, if necessary. 8.4÷ 3 ≈ 3 28 3)8.4 -6 24 -24 0 Step 3?

31. Divide Decimals by Whole Numbers Round to the nearest tenth, if necessary. 8.4÷ 3 ≈ 3 2.8 3)8.4 -6 24 -24 0 Since we do not have a digit in the hundredths place, we do not need to round.
