O.4=2/5
2/5+2/5=4/5
1/5=72
So, 72×5 (5 is the whole) =360 stickers in all.

Paula had 360 stickers in the beginning.

I hope this helps!

So Paula sold 2/5 of her tickets initially. Of the "remaining" tickets (remainder is the key word here) she gave 2/5 to her friend. So this means after selling her tickets she had 3/5 left, which she further divided by giving her friend 2/5 of the remaining 3/5. (Hope I'm making sense so far) so what that means is, you need to figure out how many tickets were given to her friend by dividing 72/3 equaling 24. This tells you what value every 1/5 of tickets she gave her friend are. So you multiply 24•5 (the whole) giving you a product of 120. 120 is how many tickets she had left after selling. Now you divide 120/3 (the tickets not sold) giving you a quotient of 40. 40 represents the value of 1/5 tickets, so to find the original sum of tickets you would multiply 40•5 equaling to 200 tickets in total. Hope that drawn out explanation made sense!
