Step-by-step explanation:
Given:
We need 5 liters of Yoda soda for 12 guest.
To find:
If we have 36 guest how many liters of Yoda soda we need.
Solution:
<u>By unitary method:</u>
For 12 guests, we need liters of Yoda soda = 5
For 1 guest, we need liters of Yoda soda = 
For 36 guests, we need liters of Yoda soda = 
Therefore, we need 15 liters of Yoda soda for 36 guests.
If 5/3% of some number is 4.75, then 1/3% of that number would be 4.75/5. Then multiply that answer by 3 to get 3/3=1% of the number, and finally multiply by 100 to get 100%.
