To find out how many grams of salt each recipe gets, you need to divide the total amount of salt by the number of recipes.
So, you will calculate:
\[ \text{Amount of salt per recipe} = \frac{64 \text{ grams}}{10} \]
Calculating that gives:
\[ \text{Amount of salt per recipe} = 6.4 \text{ grams} \]
Therefore, each recipe gets 6.4 grams of salt.
