Answer:
1 lb of fresh tomatoes yields 1.5 cups cooked tomatoes.
Step-by-step explanation:
Write out:
10 lb fresh tomatoes  ↔  15 cups cooked tomatoes.
We want the yield in cooked tomatoes of 1 lb fresh tomatoes. Â To obtain this, divide both sides by 10, obtaining
10 lb fresh tomatoes        15 cups cooked tomatoes
-------------------------------  ↔  -------------------------------------------
        10                         10
So 1 lb of fresh tomatoes yields 1.5 cups cooked tomatoes.
