    1 3/4 for each batch to make 2 1/2 batches you need to take the amount of raisins for one batch 1 3/4 and multiply it by 2 1/2 the amount of batches.

    1 3/4*2 1/2 = 4 3/8 cups of raisins

    Adrian will need: 1 and 3/7 cups of raisins

    1) Divide 2 and 1/2 by 1 and 3/4

    2) You make both fractions improper fractions

    =2 and 1/2 = 5/2

    =one and 3/4 = 7/4

    3) Use the rule KCF K=Keep C=Change F=Flip

    4) Keep = 5/2

    5) Change = * becomes a divide sign

    6) Flip=7/4 becomes 4/7

    7) Multiply across

    =5*4=20

    =2*7=14

    =20 over 14

    8) Change 20 over 14 into a mixed fraction

    9) Divide 10 by 7

    =1 with the remainder of 3

    10) 1 is the whole number 3 is the numerator and 7 is the denominator
