Dividing Decimals 5.NBT.B.7

2
÷2=0.84 0.42 What decimal does this represent? How many hundredths are filled in?Eighty …… fourThis represents 84 hundredths.Now, let’s divide the decimal 0.84 by 2.The result is 2 groups of 0.42.So, 0.84 ÷ 2 = 0.42.Now, what decimal does each group show? Dividing Decimals

3
÷3=0.75 0.25 Seventy …… fiveThis represents 75 hundredths.Now, let’s divide the decimal 0.75 by 3.The result is 3 groups of 0.25.So, 0.75 ÷ 3 = 0.25.Now, what decimal does each group show?What decimal does this represent? How many hundredths are filled in? Dividing Decimals

4
÷4=0.56 0.14 Fifty …… sixThis represents 56 hundredths.Now, let’s divide the decimal 0.56 by 4.The result is 4 groups of 0.14.So, 0.56 ÷ 4 = 0.14.Now, what decimal does each group show?What decimal does this represent? How many hundredths are filled in? Dividing Decimals

5
90 54..5 What is 45 divided by 5?9Here is 4.5 divided by 5.We divide the decimals the same way as whole numbers.But now there is a decimal point that we need to mark in the correct place.We mark the decimal point straight above in the same place.Let’s mark the decimal point right here.Since there is no number in the ones place, let’s mark a zero here.4.5 divided by 5 is 0.9. Dividing Decimals

6
40 23..8 What is 32 divided by 8?4Here is 3.2 divided by 8.Let’s mark the decimal point directly above...… and place it right here.Since there is no number in the ones place, let’s mark a zero here.3.2 divided by 8 is 0.4. Dividing Decimals

7
7 5 171..3 171 divided by 3 is …… 57Here is 17.1 divided by 3.Let’s mark the decimal point directly above...… and place it right here.17.1 divided by 3 is 5.7. Dividing Decimals

8
3 2 960..3 0 69 divided by 3 is …… 23Here is 0.69 divided by 3.Let’s mark the decimal point directly above...… and place it right here.0.69 divided by 3 is 0.23.Since there is no number in the ones place, let’s mark a zero here. Dividing Decimals

9
4 0 630..90. Before we mark the decimal point, let’s simply divide the numbers.4Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.0.36 divided by 0.9 is 0.4.Since there is no number in the ones place, let’s mark a zero here.Here is 0.36 ÷ 0.9. Notice that both the divisor and the dividend are decimals.What is 36 divided by 9?First, let’s move the decimal point in the divisor one place the right.Then, we must also move the decimal point in the dividend one place to the right to match. Dividing Decimals

10
6 0 240..70. Before we mark the decimal point, let’s simply divide the numbers.6Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.0.42 divided by 0.7 is 0.6.Since there is no number in the ones place, let’s mark a zero here.Here is 0.42 ÷ 0.7. Notice that both the divisor and the dividend are decimals.What is 42 divided by 7?First, let’s move the decimal point in the divisor one place to the right.Then, we must also move the decimal point in the dividend one place to the right to match. Dividing Decimals

11
7 0 120..30. Before we mark the decimal point, let’s simply divide the numbers.7Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.0.21 divided by 0.3 is 0.7.Since there is no number in the ones place, let’s mark a zero here.Here is 0.21 ÷ 0.3. Notice that both the divisor and the dividend are decimals.What is 21 divided by 3?First, let’s move the decimal point in the divisor one place to the right.Then, we must also move the decimal point in the dividend one place to the right to match. Dividing Decimals

12
8 420..30.0 Before we mark the decimal point, let’s simply divide the numbers.8Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.0.24 divided by 0.03 is 8.Since there are no digits in the decimal places, let’s erase the decimal point. The quotient is simply 8.Here is 0.24 ÷ 0.03. Notice that both the divisor and the dividend are decimals.What is 24 divided by 3?First, move the decimal point in the divisor two places to the right.Then, we must also move the decimal point in the dividend two places to the right to match. Dividing Decimals

13
0 9 045..60. Before we mark the decimal point, let’s simply divide the numbers.9Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.54 divided by 0.6 is 90.Since there are no digits in the decimal places, let’s erase the decimal point. The quotient is simply 90.Here is 54 ÷ 0.6.What is 54 divided by 6?If we move the decimal point in the divisor one place to the right …… we must also move the decimal point in the dividend one place to the right to match.54 is the same as 54 and 0 tenths.Now, let’s move the decimal point one place.There are no ones in the quotient.So let’s mark a zero in the ones place.Since there is no decimal point, let’s mark where it would be. Dividing Decimals

14
0 2 041..70.0 Before we mark the decimal point, let’s simply divide the numbers.2Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.1.4 divided by 0.07 is 20.Since there are no digits in the decimal places, let’s erase the decimal point. The quotient is simply 20.Here is 1.4 ÷ 0.07.What is 14 divided by 7?If we move the decimal point in the divisor two places to the right …… we must also move the decimal point in the dividend two places to the right to match.There are no ones in the quotient.So let’s mark a zero in the ones place. Dividing Decimals

9 0 810..20. Before we mark the decimal point, let’s simply divide the numbers.9Now, let’s manage the placement of the decimal point.Let’s mark the decimal point directly above...… and place it right here.0.18 divided by 0.2 is 0.9.Since there is no number in the ones place, let’s mark a zero here.Here is 0.18 ÷ 0.2. Notice that both the divisor and the dividend are decimals.What is 18 divided by 2?If we move the decimal point in the divisor one place to the right …… we must also move the decimal point in the dividend one place to the right to match.
