edward’s recipe for salad uses a ratio of 2 1/4 cups of lettuce to 1/2 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)/(1/2)
b.
For one pound of tomatoes we would end up doubling the recipe.
The equation would look like this 
2((9/4)/(1/2)
You would distribute and get
(18/4)/(2/2)
which when simplified once is
(9/2)/(1)
but once simplified even more you get your answer.
4.5 cups of lettuce for 1 cup of tomatoes

The equation is  125+22m=b
