Answer:
Each friend will get [tex]\frac{9}{25}[/tex] of the flat of flowers.
Step-by-step explanation:
Johan buys 3 flats of flowers.
He plants [tex]\frac{2}{5}[/tex]th of the flowers, then the remaining flowers = 3 - [tex]\frac{2}{5}\times 3[/tex]
= [tex]\frac{9}{5}[/tex]
Now he divides the remaining flowers among 5 friends.
So each friend gets the fraction of flowers = [tex]\frac{\text{Remaining flowers}}{\text{Number of friends}}[/tex]
= [tex]\frac{\frac{9}{5} }{5}[/tex]
= [tex]\frac{9}{25}[/tex]
Therefore, each of Johan's friend will get [tex]\frac{9}{25}[/tex] of the flat of flowers.
