This is a Fraction question.
First you draw 5 boxes and write 60 at the end.
Next you do 60 ÷ 5 = 12 and write 12 in one box.
Then you do 12 x 3 = 36 and that is the answer.
I think this is for Primary 4. Are you sure you are only Primay 3?
If you are, your teacher must be lucky to teach genius class.
