Given:
1 3/4 cups of raisins for one batch of muffins
Adrian needs to make 2 1/2 batches of muffins for bake sale.
Convert the mixed fractions into improper fractions:
1 3/4 = ((14)+3)/4 = 7/4
2 1/2 = ((22)+1)/2 = 5/2
Multiplying fractions:
1) Multiply numerators
2) Multiply denominators
3) Simplify answer
7/4 5/2 = 75 / 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.
