1 Divide Rational Numbers With models

2 Dividend Divisor Quotient Dividend DivisorQuotient ÷= Total Pieces GroupsHow many in each group ÷= Total Pieces GroupsHow many in each group ÷=

3 Divide 8 ÷ 4 This means to take 8 items and put them into 4 equal groups The quotient is how many in one group = 2 How many in each group? Divide 8 ÷ 4 This means to take 8 items and put 4 into each group The quotient is how many groups = 2 How many groups ?

4 Divide 0.8 ÷ 4= 0.2 Divide 0.8 ÷ 0.4= 2 Pick the way that is easiest for the problem Divide 0.8 ÷ 0.2= 4 Divide 0.8 ÷ 2= 0.4

5 Divide 0.8 ÷ 4 = 0.2 Divide 8/10 ÷ 4 Re - write as a Fraction 4/5 = 1/5 0.2 = 1/5 Divide 1/6 ÷ 3 = 1/18 How many fours do you have 1 1 1 1 4/20 = 1/5

6 2 ÷ 1/3 =6 How many thirds are in 2 whole 4 ÷ 2/3 = Cut the whole by 3 Count the 2/3 6

10 Divide 0.8 ÷ 4= 0.2 Divide 0.8 ÷ 0.4= 2 Pick the way that is easiest for the problem Divide 0.8 ÷ 0.2= 4 Divide 0.8 ÷ 2= 0.4

11 Divide 0.8 ÷ 4 = 0.2 Divide 8/10 ÷ 4 Re - write as a Fraction 4/5 = 1/5 0.2 = 1/5 Divide 1/6 ÷ 3 = 1/18 How many fours do you have 1 1 1 1 4/20 = 1/5

12 2 ÷ 1/3 =6 How many thirds are in 2 whole 4 ÷ 2/3 = Cut the whole by 3 Count the 2/3 6
