Answer:
Sheldon have left [tex]2\frac{7}{12}\ kg[/tex] of food.
Step-by-step explanation:
Quantity of food = [tex]4\frac{1}{2}=\frac{9}{2}[/tex] kg
Quantity used on strawberry plant = [tex]1\frac{2}{3} = \frac{5}{3}\ kg[/tex]
Quantity used on tomato plant = [tex]\frac{1}{4}\ kg[/tex]
Food left = Total - used on strawberry - used on tomato
Food left = [tex]\frac{9}{2}-\frac{5}{3}-\frac{1}{4}[/tex]
Food left = [tex]\frac{54-20-3}{12} = \frac{31}{12}[/tex]
Food left = [tex]2\frac{7}{12}\ kg[/tex]
Therefore,
Sheldon have left [tex]2\frac{7}{12}\ kg[/tex] of food.
