Answer: 3 7/12
Explanation:
From the question, we are given the information that Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour.
The number of cups of flour that they have altogether would be the addition of all the fractions of each girl. This would be:
= 1 1/2 + 3/4 + 1 2/6
The lowest common multiple is 12, therefore we make them have a common denominator
= 1 6/12 + 9/12 + 1 4/12
= 2 19/12
= 2 + 1 7/12
= 3 7/12 cups
