Adrian will need 4 3/8 cups of raisins to bake 2 1/2 batches.

Convert the mixed fractions into improper fractions:

1 3/4 = 7/4

2 1/2 = 5/2

Multiplying fractions:

1) Multiply numerators

2) Multiply denominators

3) Simplify answer

7/4 * 5/2 = 7*5 / 4*2 = 35/8

35/8 can be simplified into a mixed fraction 4 3/8 

Adrian needs to use 4 3/8 cups of raisins.

Answer:

4 3/8

Step-by-step explanation:

Step 1: Convert the numbers into improper fractions. To do this, multiply the denominator value by the whole number and then add the numerator to that product. 1 3/4 becomes 7/4 and 2 1/2 becomes 5/2.

Step 2: Multiply the fractions straight across. Multiply the numerators together and the denominators together. 7 * 5 is 35. 4 * 2 is 8. The improper fraction is 35/8.

Step 3: Convert the improper fraction to a mixed number. Do this by dividing the numerator by the denominator. 35/8 is 4 with a remainder of 3/8. 4 3/8 is the number of cups he will use to make his batches of muffins.
