3. Edward's recipe for salad uses a ratio of cups of lettuce to lb of tomatoes. (a) Use a complex fraction to compare the amount of lettuce to the amount of tomatoes. (b) Determine how many cups of lettuce Edward needs to mix with 1 lb of tomatoes. Show your work.

A.

(9/4) cups of lettuce / (1/2) lb of tomotoes

b.

For one pound of tomatoes, the recipe will be doubled.

multiplying the ratio by 2/2, the ratio would be:

2 ((9/4) / (1/2)

distributing the 2/2

(18/4) / (2/2)

which when simplified once is

(9/2) / (1)

so reducing to decimal form, so:

4.5 cups of lettuce for 1 cup of tomatoes
