Fractions: Multiplication and Division

Day 1: Multiply Fractions Intro

1

3/5 x 4/6

12/30 = 2/5

2

7/10 x 5/9

35/90 = 7/18

3

9/12 x 8/14

72/168 = 36/84 = 18/42 = 3/7

4

12/15 x 14/18

168/270 = 28/45 (reduced)

5

19/23 x 13/21

247/483

Day 2: Multiply Fractions Advanced

1

2/5 x 3/8 x 4/6

24/240 = 1/10

2

6/10 x 9/12 x 5/6

270/720 = 27/72 = 3/8

3

12/15 x 3/5 x 9/12

324/900 = 9/25

4

1 5/9 x 6/10 =

84/90 = 42/45 = 14/15

5

2 8/12 x 2 6/8 =

32/8 x 22/8 = 8/3 x 11/4 (reduced for ease)

88/12 /4 = 22/3 = 7 1/3

Day 3: Divide Fractions Intro

1

8/12 -:- 3/5

40/36 = 1 1/9

2

8/15 -:- 5/7

56/75

3

12/18 -:- 4/9

108/72 = 1 1/2

4

15/20 -:- 10/25

375/200 = 1 7/8

5

19/30 -:- 21/28

532/630 = 38/45

Day 4: Divide Fractions Advanced

1

7/8 -:- 5/6

42/40 = 1 1/20

2

9/12 -:- 8/14

126/96 = 1 5/16

3

13/17 -:- 21/23

299/357 (cannot reduce)

4

1 7/12 -:- 1 6/9

19/12 x 15/6 (reduce now for a smaller product)

19/12 × 5/2 = 95/24

3 23/24

5

3 8/12 -:- 2 10/14

44/12 -:- 38/14 (reduce for a smaller product)

11/3 x 19/7 = 209/21 =

9 20/21
