Paula sold 0.4 of her stickers. she gave her friend 2/5 of the remainder. paula remained with 72 stickers. calculate how many stickers paula had at the beginning?

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!

Ithink it is correct but just ask someone else but i am sure it it
