2. When Franz gave 342 stamps to Gabriel, Gabriel had 7 times as many stamps as what Franz had left. If they had an equal number of stamps at first, how many stamps did Gabriel have in the end?

Kindly teach me how to draw model for these 2 qns.

Let me give a try :lol:
3 files = 2 books
6 files = 4 books

5 books (Draw a model of 5 units - take as 1 whole unit) + 6 files (Draw a model of 6 units - take as 1 whole unit) - $171
Therefore,
5 books, 1 whole unit = $171
5 books + 4 books = $171
9 books = $171

Therefore, the cost of 1 book is $171 / 9 = $19
5 books = 5 x $19 = $95

Sorry, I am very computer-retarded so I unable to draw out the model. Perhaps some other experts can assist you :imanangel:
