To find the number of cups of onion needed, we need to determine the part of the extended ratio that represents onion and then multiply it by the total cups of salsa.
The extended ratio is 1 : 3 : 9, which means that for every 1 part of green pepper, there are 3 parts of onion and 9 parts of tomato.
Since 3 parts of onion correspond to 117 cups of salsa, we need to divide 117 by 3 to find the number of parts of onion.
117 cups / 3 = 39 cups
Therefore, 39 cups of onion are needed to make 117 cups of salsa.
