The total whole number area of the square = 1.
Part A + Part B + Part C = 1.
1/3 + 2/5 + C = 1.
(5+ 6)/15 + C = 1. LCM of 3 and 5 is 15.
11/15 + C = 1.
C = 1/1 - 11/15 = (15 -11)/15
C = 4/15.

1/3= 5/15 2/5= 6/15
5/15 + 6/15 = 11/15
15/15 - 11/15 = 4/15
Part C= 4/15
Parts A and B combined make up 15 11 of the area of the square. By subtracting this from the total area of the square, we find that part C occupies 15 4 of the area. Thus, part C is 15 4 of the total area of the square.
