Erika and Joelle used the same number of strawberries to bake cakes. Erika used ³₄ of her strawberries and Joelle used ⁵₈ of her strawberries. They had a total of 88 strawberries at first.

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

	Erika	Joelle	Total
Before	4x5 = 20 u	8x3 = 24 u	44 u
Change	- 3x5 = - 15 u	- 5x3 = - 15 u
After	1x5 = 5 u	3x3 = 9 u	14 u

(a)
Erika and Joelle used the same number of strawberries to bake cakes.  Make the numerators the same. LCM of 3 and 5 is 15. 
3x54x5 of Mary's strawberries = 5x38x3 of Joelle's strawberries 
1520 of Mary's strawberries = 1524 of Joelle's strawberries 

Total number of strawberries at first
= 20 u + 24 u
= 44 u

44 u = 88

1 u = 88 ÷ 44 = 2

Number of strawberries that each girl used
= 15 u
= 15 x 2
= 30 

(b)
Total number of strawberries that both girls had left 
= 5 u + 9 u
= 14 u
= 14 x 2
= 28

Answer(s): (a) 30; (b) 28
