Betty and Shannon used the same number of strawberries to bake cakes. Betty used ²₅ of her strawberries and Shannon used ³₅ of her strawberries. They had a total of 125 strawberries at first.

1. How many strawberries did each girl use?
2. How many strawberries did both girls have left altogether?

	Betty	Shannon	Total
Before	5x3 = 15 u	5x2 = 10 u	25 u
Change	- 2x3 = - 6 u	- 3x2 = - 6 u
After	3x3 = 9 u	2x2 = 4 u	13 u

(a)
Betty and Shannon used the same number of strawberries to bake cakes.  Make the numerators the same. LCM of 2 and 3 is 6. 
2x35x3 of Mary's strawberries = 3x25x2 of Shannon's strawberries 
615 of Mary's strawberries = 610 of Shannon's strawberries 

Total number of strawberries at first
= 15 u + 10 u
= 25 u

25 u = 125

1 u = 125 ÷ 25 = 5

Number of strawberries that each girl used
= 6 u
= 6 x 5
= 30 

(b)
Total number of strawberries that both girls had left 
= 9 u + 4 u
= 13 u
= 13 x 5
= 65

Answer(s): (a) 30; (b) 65
