In a kiosk, some jigsaw puzzles and frisbees were on sale. ¹₅ of the items were jigsaw puzzles. ²₃ of the jigsaw puzzles and 147 frisbees were sold. There were ¹₆ of the items left in the kiosk. How many jigsaw puzzles and frisbees were there in the kiosk at first?

	Jigsaw puzzles	Frisbees	Total
Comparing jigsaw puzzles  and frisbees at first	1x6 = 6 u	4x6 = 24 u	5x6 = 30 u
Before	3x2 =  6 u		6x5 = 30 u
Change	- 2x2 = - 4 u	- 147	- 5x5 = - 25 u
After	1x2 = 2 u	3 u	1x5 = 5 u

 
The total number of toys at first is repeated.  Make the total number of toys at first the same. LCM of 5 and 6 is 30.

The number of jigsaw puzzles at first is repeated.  Make the number of jigsaw puzzles the same. LCM of 6 and 3 is 6. 

Number of frisbees left
= 5 u - 2 u
= 3 u

Number of frisbees sold
= 24 u - 3 u
= 21 u

21 u = 147

1 u = 147 ÷ 21 = 7

Number of jigsaw puzzles and frisbees at first
= 30 u
= 30 x 7
= 210

Answer(s): 210
