You can use a proportion.
A proportion is setting two ratios equal.
The known ratio is 5 grapes to 2 strawberries, or 5/2.
The unknown ratio is x grapes to 14 strawberries, or x/14.
Set these ratios equal creating a proportion, and solve for x.
\(\dfrac{5}{2} = \dfrac{x}{14} \)
Now cross multiply and solve for x.
