Problema Solution
Luisa and Emelinda each made a bowl of punch. Emelinda used 4 4/5 times as much lemonade as Luisa did. If Luisa used 4/5 of a cup of lemonade, how many cups of lemonade did Emelinda use?
Answer provided by our tutors
Luisa used 4/5 of a cup of lemonade
Emelinda used 4 4/5 times as much lemonade as Luisa did:
(4 4/5)*(4/5) = ((4*5 + 4)/5)*(4/5) = (24*4)/(5*5) = 96/25 = 3 21/25 cups of lemonade
Emelinda used 3 21/25 cups of lemonade.
