In order to determine how many servings of rice Celia makes, multiply 2/3 by 3 1/2. However, first express the number 3 1/2 as a normal fraction:
3 1/2 = 3/1 + 1/2 = (6 + 1)/2 = 7/2
next, multiply 7/2 by 2/3:
7/2 x 2/3 = 14/6 = 7/3
Hence, Celia made 7/3 servings of rice.
7/3 can be also written as a mixed number, a follow:
7/3 = 2 1/3
