Fraction Level 3.

I am learning to solve fraction problems at level 3.

This task is about finding fractions of a given number.
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 sells.
  • Half of 72 = 36 which is 2/4 of 72.
  • Half of 36 is 18 so then 18 is 1/4.
  • The answer is, the farmer sells 18 cows.
     Answer- The farmer sells 18 cows.


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


  • Put into 45 into 3 groups.
  • So each group will have 15 pigs.
  • Because 15 + 15 + 15 = 45.
  • So the farmer sells 15 pigs.
Answer-  The farmer sells 15 pigs



3.   He sells ⅙ of his 84 sheep.  Show how to work out how many sheep he sells.
   
  • First I share 84 into 6 groups.
  • I firstly put 10 into the 6 group.  Then I have 24 left.
  • I  divide 24 into 6 groups = 4.  Therefore 10 + 4 = 14.
  • 14 sheeps is 1/6 of 84 sheeps.
Answer-14 sheeps sold.
