Fractions

I am able to work out Fraction problems in level 3.

A farmer is selling some of his animals.

1.  The farmer sells ¼ of his 72 cows.  Show how to work out how many cows he Sell.

1/4 of 72.

72 divided by 4= 18

18 x 1 = 18

4 x 18 = ?

2 x 18 = ?

2 x 10 = 20

2 x 8 = 16

20 +16 = 36

36 doubled = 72

4 x 18 = ?

2 x 18 = ?

2 x 10 = 20

2 x 8 = 16

20 +16 = 36

1/2 of 36 is 18

36 doubled = 72 = 144

2. He sells ⅓ of his 45 pigs.  Show how to work out how many pigs he sells.
