Final answer:
To find out how many tbsp of parsley Fabiola needs for her special seasoning mix, calculate the ratio of parsley to the total number of parts and then multiply the proportion by the total amount of the mix.
Step-by-step explanation:
To determine how many tbsp of parsley Fabiola needs for her special seasoning mix, we need to first calculate the ratio of parsley to the total number of parts. The total number of parts in the mix is 5 + 3 + 1 = 9. To find out the proportion of parsley, we divide the number of parts of parsley by the total number of parts: 3 / 9 = 1/3.
Next, we multiply the proportion of parsley by the total amount of the mix to find out how many tbsp of parsley Fabiola needs: (1/3) x 45 = 15 tbsp.
Therefore, Fabiola needs 15 tbsp of parsley for her special seasoning mix.
