Answer: 9/16
Step-by-step explanation: First, take the number of cups and divide by the number of servings. So we have 2 and 1/4 ÷ 4.
Now, rewrite 2 and 1/4 as the improper fraction 9/4 an 4 as 4/1.
So we have 9/4 ÷ 4/1.
Now, dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction. So 9/4 ÷ 4/1 can be rewritten as 9/4 × 1/4.
Now, multiply across the numerators and denominators to get 9/16.
So there are 9/16 cup of raisins in each serving.
