Fraction and division in arrays

 

 

In class we have learnt about fractions in division. We used counters to solve the division problem. This is my array.

The fraction that I wanted to find first was 1/2 of 60. So what I did was divide 60 by 2 which is 30. Next I had to find out what was 1/15 of 60. So once again I divided 60 by 4 which is 15. Finally I had to find out what 1/15 of 60 was. So finally I divided 60 by 15 which equaled 4.

Do you know any other strategies to solve these problems?

Have you ever tried this technique?
