Equal concept?

by Angie

There were 920 spectators in the sports hall watching a badminton match. After 2/5 of the children and 2/7 of the adults left the hall, the number of children and the number of adults remaining in the hall were the same. How many children remained in the hall?

How can I show my girl the solution via models?
