Given:
Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg
Rotten tomatoes = 1.5 kg
To find:
How many kilograms of tomatoes were not rotten?
Solution:
Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg
= [tex]\dfrac{4(10)+4}{10}[/tex] kg
= [tex]\dfrac{40+4}{10}[/tex] kg
= [tex]\dfrac{44}{10}[/tex] kg
= [tex]4.4[/tex] kg
Rotten tomatoes = 1.5 kg
Remaining tomatoes which are not rotten is
Required tomatoes = Tomatoes Sheldon picks - Rotten tomatoes
= [tex]4.4-1.5[/tex]
= [tex]2.9[/tex] kg
Therefore, the tomatoes which were not rotten is 2.9 kg.
