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) Complex fractions contain fractions as the numerator and denominator. For example, Edward's recipe for salad requires 3 3/4 cups of lettuce to 1 1/2 pounds of tomatoes.. Then the ratio would be



(b) We convert the complex fractions to improper fractions. The numerator would be (denominator*whole number)+numerator. The denominator remains as is.

3 3/4 = [(3*4)+3]/4 = 15/4
1 1/2 = [(2*1)+1]/2 = 3/2

So, if Edward has 1 lb of tomatoes,





Therefore, Edward needs 5/2 cups of lettuce.

B, 0.4 repeats so it is rational and square root of 16 is 4 so that is rational as well.
