A salsa recipe uses green pepper, onion, and tomato in the extended ratio 2:3:7. How many cup of onion are needed to 60 cups of salsa?

We can begin by setting up a proportion:

2/12 (2/12 is equal to 1/6 because 2 + 3 + 7 = 12) = x/60

To solve for x, we can cross-multiply:

2/12 * 60 = x

x = 10

Therefore, 10 cups of onion are needed for 60 cups of salsa.

To find out how many cups of onion are needed for 60 cups of salsa, we first need to determine the ratio of onion to salsa.

The extended ratio of green pepper, onion, and tomato is given as 2:3:7. This means that for every 2 parts of green pepper, there are 3 parts of onion and 7 parts of tomato.

To calculate the ratio of onion to salsa, we need to consider the 3 parts of onion for every 12 (2+3+7) parts of the mixture, as this represents the total proportion of onion.

So, the ratio of onion to salsa is 3:12, which can be simplified as 1:4.

Now, to find out how many cups of onion are needed for 60 cups of salsa, we divide the total volume (60 cups) by the total parts of the ratio (4 parts).

Number of cups of onion = (Total cups of salsa / Total parts of the ratio) * Parts of onion
= (60 cups / 4) * 1
= 15 cups

Therefore, 15 cups of onion are needed for 60 cups of salsa.
