Ответ:
If Ethan has half of $90. You would have to divide $90 by 2, giving you $45.
And if Chris has a third of $90. You would have to divide $90 by 3, giving you $30.
Now, Chris. That leaves Chris with the rest of the money missing that adds up too $90. So if, $45 plus $30 equals $75. Subtract $75 from $90 which gives you $15 left.
Hope I helped!!

It's B
The perimeter of Rectangle BCDA is 30.
The perimeter of the smaller rectangle is 22.
30/22 simplifies to 15/11
