State how many there are in all for a division problem

Share in equal groups

Ask the question to find out how many are in each group. I would write a question like this:

• There were 14 cookies on the tray Justin wanted to share them with Oscar. How many cookies did each boy get?

  
  

  Each boy got 7 cookies because 14 divided by 2 equals 7

• There were 2 cookies on the tray Angel wanted to share them with Axel, Brandon and Dilan. How many cookies did each boy get?

  
  

  Each boy got 4 cookies because there are 4 boys

• Two times 7 equals fourteen so I would just write this.
