It's incorrect.

At first , Hanna has 5 units of stamps. Ashley has 1 unit.

Total = 6 units
6 units ÷ 2 = 3 units

When they have equal number of stamps, each girl has 3 units.

5 units - 3 units = 2 units.
This means Hanna gave 2 units of stamps to Ashley.

2 units = 84 stamps
1 unit = 84 stamps ÷ 2 = 42 stamps

Number of stamps Hanna has at first
= 42 x 5 = 210

Take note that they are gonna have the same number of stamps at the end, so they should both have 3 units at the end.
In case you are unsure, you can always sub the numbers back to check!
Have a good day. :)
