19. Multiplying Fractions
To multiply simply times the numbers at the top, then times the numbers at the bottom, you may have to simplify 3 4 5 8 15 32 x = 2 7 5 6 10 42 5 21 x = = 3 5 7 9 21 45 7 15 x = =

20. Simplify before multiplying1 6 7 5 6
1x5
7x1 5 7 x =
This will help with division too, do it after the keep, change flip bit = 1 1 4 5 3 8
1x3
5x2 3 10 x = = 2 2 4 9 6 7
4x2
3x7 8 21 x = = 3

22. Dividing Fractions 4 7 3 4 4 7 4 3 16 21 ÷ = x = 1 2 7 8 1 2 8 7 8 14
To divide remember KEEP, CHANGE, FLIP
KEEP the first fraction
CHANGE the multiply sign to divide
FLIP the second fraction 4 7 3 4 4 7 4 3 16 21 ÷ = x = 1 2 7 8 1 2 8 7 8 14 4 7 ÷ = x = = 3 4 5 8 3 4 8 5 24 20 ÷ 1 5 = x = =1 4 20 1 or

42. Cancelling fractions down
It is often best to have the numbers possible when we write fractions
12 20 3 5
Instead of
we would have
We have cancelled the fractions down, by dividing top and bottom numbers by the same number (in this case 4)

43. 15 35 3 7 =
Divide by 5
24 36 2 3 =
Divide by 12
55 66 5 6 =
Divide by 11

44. Cancelling fractions down
If we pick the biggest number possible to divide by we only have to cancel down once. We must always check that there are no more numbers which go into the top and bottom number When there are no more numbers which go into the top and bottom of the fraction, the fraction is FULLY SIMPLIFIED or CANCELLED DOWN FULLY

57. Mixed numbers and top heavy fractions
When you see a fraction with a large number in front of it, this is a MIXED NUMBER. 2 2 3
This mean, 2 and 2 thirds
When we have a fraction where the number at the top (NUMERATOR) is bigger than the number at the bottom (DENOMINATOR) we have a TOP HEAVY FRACTION 5 3 8 4 9 2

58. Mixed numbers and top heavy fractions
You need to be able to:
turn MIXED NUMBERS into TOP HEAVY FRACTIONS
turn TOP HEAVY FRACTIONS into MIXED NUMBERS

59. Top heavy fractions to mixed numbers14 3
How many 3’s go into 14? 4
What is the remainder? 2
So we can make 4 wholes and we have 2 thirds left over: 14 3 = 4 2 3

60. Top heavy fractions to mixed numbers19 5
How many 5’s go into 19? 3
What is the remainder? 4
So we can make 3 wholes and we have 4 fifths left over: 19 5 = 3 4 5

61. Top heavy fractions to mixed numbers31 10
How many 10’s go into 31? 3
What is the remainder? 1
So we can make 3 wholes and we have 1 tenth left over: 31 10 = 3 1 10

62. Mixed Numbers to Top heavy fractions
To turn the mixed numbers into top heavy fractions: 3 1 10 31 10 =
Multiply these numbers together= 30
Add on the number at the top=
31 (this will be the top number)
The number at the bottom will stay the same

63. Mixed Numbers to Top heavy fractions
To turn the mixed numbers into top heavy fractions: 5 3 4 23 4 =
Multiply these numbers together= 20
Add on the number at the top=
23 (this will be the top number)
The number at the bottom will stay the same

64. Mixed Numbers to Top heavy fractions
To turn the mixed numbers into top heavy fractions: 6 2 5 32 10 =
Multiply these numbers together= 30
Add on the number at the top=
32 (this will be the top number)
The number at the bottom will stay the same
