There were 5 pomegranates more than starfruits in a fruit stall. ¹₂ of the starfruits and ³₅ of the pomegranates were sold. Given that there was an equal number of starfruits and pomegranates left, how many starfruits were there in the fruit stall at first?
Fraction of the starfruits left
= 1 - ¹₂
= ¹₂

Fraction of the pomegranates left
= 1 - ³₅
= ²₅

The number of starfruits and pomegranates left is the same. Make the number of pomegranates and starfruits left the same. LCM of 1 and 2 is 2.

1x22x2 of the starfruits = 2x15x1 of the pomegranates
24 of the starfruits = 25 of the pomegranates

Number of starfruits at first = 4 u
Number of pomegranates at first = 5 u

Number of more pomegranates than starfruits at first
= 5 u - 4 u
= 1 u
= 5

Number of starfruits at first
= 4 u
= 4 x 5
= 20

Answer(s): 20
