Answer:

Sheldon have left $2\frac{7}{12}\ kg$ of food.

Step-by-step explanation:

Quantity of food = $4\frac{1}{2}=\frac{9}{2}$ kg

Quantity used on strawberry plant = $1\frac{2}{3} = \frac{5}{3}\ kg$

Quantity used on tomato plant = $\frac{1}{4}\ kg$

Food left = Total - used on strawberry - used on tomato

Food left = $\frac{9}{2}-\frac{5}{3}-\frac{1}{4}$

Food left = $\frac{54-20-3}{12} = \frac{31}{12}$

Food left = $2\frac{7}{12}\ kg$

Therefore,

Sheldon have left $2\frac{7}{12}\ kg$ of food.
