Adrian recipe

for raisin muffin calls for one and three fourth cups raisins for one batch of muffins Adrian wants to make 2 1/2 batches of the muffins for a bake sale how many cups of raisins will Adrian use

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
